Question What is the Composr Member System?
Answer The Composr Member System is the system used by the Conversr forum software to manage user accounts and information. This includes usernames, passwords, profile information, and usergroups. It also handles user registration, login, and account management. For websites not using Conversr, the member system of the third-party forum software would be used.
Question Can I Use Composr Galleries to Publish Podcasts?
Answer Yes, Composr supports creating podcasts from galleries. The podcast URL follows this format: http://yourbaseurl/backend.php?mode=galleries&select=galleryname&type=rss&itunes=1. Replace yourbaseurl and galleryname accordingly. This URL can be used to subscribe to the podcast in iTunes or other podcast applications.
Question How Do Gallery Slide-shows Work?
Answer When viewing an image or video in a gallery, visitors can initiate a slide-show that automatically cycles through subsequent entries. The slide-show can be paused with a click or keypress. The default slide-show speed can be adjusted by modifying the GALLERY_ENTRY_SCREEN.tpl template.
Question What are Watermarks and How Do They Work?
Answer Watermarks are semi-transparent images overlaid on gallery images to mark their origin or deter unauthorized use. When you add or edit a gallery, you can choose to apply watermarks to the corners of images. Watermarking applies permanently to the uploaded image. Composr uses a reverse tree structure for watermarks: if a sub-gallery doesn't have a watermark defined, it inherits the watermark from its parent gallery.
Question Can Members Create Their Own Personal Galleries?
Answer Yes, members with the "have personal galleries" permission can create their own galleries. These personal galleries are displayed under designated "Personal category container" galleries. They also show up in a tab on the member's profile. Members can only add content to their own galleries unless they have the "Submit to categories belonging to other members" permission.
Question What are Rep-Images and How Do I Set Them?
Answer Rep-images, short for "representative images," are thumbnails that represent a gallery when it's displayed within a list of galleries. They offer a visual preview of the gallery's contents. You can set a rep-image when adding or editing a gallery, or when adding an image to a gallery.
Question How Do I Import Images in bulk into a Gallery?
Answer You can import images in bulk using a CSV file. The file should be named descriptions.csv and placed in the uploads/galleries directory. The first column should contain filenames (without the path), and the second column should contain descriptions. The filenames should correspond to images also located in the uploads/galleries directory. Composr will automatically match the descriptions to the images during import.
Question What Image and Video Formats are Supported?
Answer Images:
  • .jpg/.jpeg: Highly compressed, best for photos due to minimal noticeable quality loss.
  • .png: Good compression with no quality loss, ideal if bandwidth isn't a concern.
  • .gif: Limited to 256 colors and poor compression. Better alternatives are video or APNG.
Note that Composr does not support SVG because hackers can leverage the XML-like structure of SVG files to compromise a website.

Videos:
  • .mp4 (h.264 aac encoding): The recommended format, widely supported.
  • .mov (h.264 aac encoding): Identical to .mp4.
  • .webm: Supported natively in most browsers, but requires plugins for Internet Explorer/Microsoft Edge and Safari.

Other formats, while they may work, are generally discouraged due to compatibility issues and lack of consistent addon or browser support.
Question What are Composr Galleries?
Answer Composr Galleries are a system for storing, organizing, and displaying images and videos. They function like categories, allowing you to group related media together. Galleries can be structured hierarchically, with sub-galleries nested under parent galleries, similar to a folder system. Each gallery has settings that control its appearance and behavior.
Question How are forums structured in Composr?
Answer Composr forums are organized hierarchically:
  • Forum Groupings: Broad categories that contain forums.
  • Forums: Contain topics related to a specific subject.
  • Sub-forums: Forums nested under other forums, providing further categorization.
  • Topics: Threads of conversation containing a series of posts.
  • Posts: Individual messages within a topic.

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.
