Question	What is post history and why is it important?
Answer	Post history tracks changes made to forum posts, including edits and deletions. This feature helps monitor for inappropriate edits or attempts to cover up spam or rule violations. Staff can review the history, restore deleted content, or even permanently erase it.

Question	Can I moderate content in Composr forums?
Answer	Yes, Composr provides various moderation tools for managing forum content. Moderators can edit or delete posts and topics, move topics between forums, close or open discussions, and validate content submitted by users who require approval. These are done in an actions dropdown on a topic, or through buttons on individual posts.

Question	What is the "black hole" technique and how does it work?
Answer	The "black hole" technique involves adding hidden fields to forms. While invisible to human users, bots often detect and fill these fields, revealing their nature. Composr uses this information to flag and block suspected spam submissions.

Question	How can I report spam in Composr?
Answer	You can report spam using the "report this" link or "report" (forum post button) feature. This alerts staff to the issue, allowing them to investigate and take appropriate action, such as deleting the spam, warning the user, or banning them. It also creates a Support Ticket between the reporter and staff in case the staff need further information.

Question	What are Remote Block Lists (RBLs)?
Answer	RBLs are third-party lists that track IP addresses associated with spamming activity. Composr can be configured to consult these lists and block or flag requests from suspicious IPs. However, relying solely on RBLs may lead to false positives, as some lists are overly broad.

Question	What are CAPTCHAs and how do they work?
Answer	CAPTCHAs are tests designed to differentiate between human users and bots. Composr's unique CAPTCHA method uses CSS and JavaScript to generate images or audio challenges that are difficult for bots to solve. While effective, some spammers use human workers to bypass CAPTCHAs, leading to the need for additional anti-spam measures.

Question	How does Composr prevent spam?
Answer	Composr offers several tools and techniques to combat spam, including: CAPTCHA: A visual or audio test that humans can easily pass but bots struggle with. This helps prevent automated spam submissions. Heuristics: If Composr thinks an action is spam based off of configurable criteria, it can either flag the content for validation, block the attempt, or ban the IP address outright. Public block lists: Composr can utilize the Stop Forum Spam system or other block list systems to identify and block known spammers based on IP addresses, usernames, and email addresses. Link posting restrictions: Disallowing links in member profiles for users with no posts and adding "nofollow" attributes to links discourages spammers seeking backlinks. Black hole fields: Hidden form fields that should remain empty. Bots often fill these in, allowing Composr to identify them. Project Honey Pot integration: A system that places hidden links on pages, attracting and identifying spam bots. Content/post reporting: Users can report spam, enabling staff to take action. Guest posting limitations: Restricting guest permissions raises the bar for spammers. Advanced techniques: Developer addons like "antispam_question" or probation systems provide additional layers of protection.

Question	What is the "Sitemap" in Composr, and how is it used?
Answer	The Sitemap is a hierarchical representation of your website's content, including zones, pages, categories, and entries. Composr generates the Sitemap dynamically and uses it for various purposes: Generating menus. Creating the user-facing sitemap page. Generating the XML Sitemap for search engines. Providing a visual representation of your website structure in the Sitemap editor and Permissions tree editor. You can edit the sitemap under Admin Zone > Structure > Sitemap editor.

Question	Can I change the URL scheme after my website is already live?
Answer	Yes, you can enable or change a URL scheme on an existing website. Old URLs will redirect to the new format, ensuring that your SEO isn't negatively impacted. The canonical URL will also be specified in your website's HTML, further protecting your search rankings.

Question	How do URL schemes work, and what are the benefits of using them?
Answer	URL schemes allow you to control the structure of your website's URLs. Composr offers several schemes that create shorter, more user-friendly URLs: /pg/ (e.g., /pg/home) .htm (e.g., /home.htm) Simple unadorned URLs (e.g., /home) Benefits of using URL schemes include: Improved user experience with more readable URLs. Potential SEO benefits, as some believe search engines favor cleaner URLs. Easier sharing on social media and other platforms.

Question	What is the purpose of "confirmed" and "non-confirmed" sessions?
Answer	Composr distinguishes between confirmed and non-confirmed sessions for added security: Confirmed: When you actively log in with your credentials. Non-confirmed: When you return to the site and are automatically logged in via cookies. You can configure zones to require confirmed sessions, preventing access from cookie-based logins alone. The Admin Zone uses this by default.

Question	How can I enhance the security of my Composr installation on shared hosting?
Answer	Shared hosting environments can be inherently less secure. Here are some tips: Choose a Secure Host: Opt for hosts that offer suEXEC and open_basedir for better account isolation. Test Security: Verify the host's security measures with the provided filesystem_browser.php script. Restrict _config.php: Remove world-writable permissions from _config.php after installation.

Question	How does Composr protect against Cross-Site Scripting (XSS) attacks?
Answer	Composr utilizes multiple layers of defense against XSS attacks: HTML Filtering: Configurable levels of filtering prevent malicious script injection. Content Security Policy (CSP): Restricts the sources from which scripts and other resources can be loaded. Input Sanitization: Data is sanitized before being processed to prevent malicious code execution. Output Encoding: Data displayed to users is properly encoded to prevent interpretation as active code.

Question	What are the different types of security alerts in Composr?
Answer	Composr has a variety of hack-attack codenames that trigger security alerts and logging. Some common examples include: DODGY_GET_HACK: Suspicious URLs with potentially harmful characters. EVIL_POSTED_FORM_HACK: Possible CSRF attempts via malicious form submissions. SCRIPT_UPLOAD_HACK: Attempts to upload PHP scripts, potentially malicious. DOWNLOAD_PRIVATE_URL_HACK/TRY_TO_DOWNLOAD_SCRIPT: Attempts to download sensitive files. BRUTEFORCE_LOGIN_HACK: Repeated failed login attempts. SQL_INJECTION_HACK: Attempts to exploit SQL queries for data extraction. You can customize alert handling for each type in data_custom/xml_config/advanced_banning.xml (Admin Zone > Security > Configure advanced banning).

Question	What are some tips for secure website maintenance?
Answer	Avoid FTP: Use secure alternatives like SFTP or SSH for file transfer. Secure Email: Enable SSL for IMAP and POP3 email protocols. Strong Passwords: Use unique and complex passwords for different services. Secure Computers: Keep your own devices patched and secure. Maintenance Password: Remove the maintenance password from _config.php when not in use.

Question	What are the main security features of Composr?
Answer	Composr has a robust set of security features to protect your website, including: Passwords: Visual representation of password quality and enforcement of complexity rules. Password expiry and prevention of re-use. Secure password hashing, even if the database is compromised. Temporary passwords for staff setup. Login Restrictions: Two-factor authentication via IP address approval. IP address banning, including wildcard banning. Session locking to IP addresses. Configurable session expiry times. Ability to prevent privileged actions from auto-logged in sessions. Optional member approval process. Auditing Systems: Comprehensive audit logging of administrative actions. Logging of user actions and IP address history. Tools to analyze audit logs. Failed login logging. Hack attack detection, logging, and banning. Email notifications for changes to user credentials. Framework Security: Protection against CSRF attacks. Click-jacking prevention via CSP implementation. Secure coding standards and scanning techniques. Configurable HTML filtering to prevent XSS attacks. Secure code modularization standards. Other features: Granular privileges and access permissions. Content submission validation process. Rootkit detection system. Spam prevention systems. Web application firewall rules. Moderation systems.

Question	Why are my searches slow, and how can I improve search speed?
Answer	Slow searches can occur when dealing with large amounts of content. Here are some workarounds and solutions: MySQL timeout setting: For MySQL 5.7+, set a query timeout to prevent searches from locking up your database. Composr automatically sets this, but you can configure it manually if needed. Use InnoDB tables: Switching to InnoDB tables in MySQL can prevent slow queries from affecting other users on your website. Note that InnoDB is not officially supported by Composr yet. Enable the fast custom index: As mentioned earlier, the fast custom index is optimized for handling large datasets and filtered searches, potentially leading to significant speed improvements.

Question	How does the search engine handle different languages?
Answer	Composr's fast custom index supports multiple languages. Content is indexed based on its translated version, ensuring that you get relevant results even when searching in a different language.

Question	What are quoted phrases and how do they work?
Answer	Quoted phrases allow you to search for an exact sequence of words. For example, searching for "red apple" will only return results containing that exact phrase. Keep in mind that enabling quoted phrases can increase disk space usage.

Question	How do stop words affect search results?
Answer	Stop words are common words (like "the", "a", "is") that are ignored by the search engine because they add noise and don't contribute to the meaning of the search query. You can customize the list of stop words for the fast custom index. See the search tutorial for more information.
