• Comcode page cache & Comcode cache: Reduces the need to parse Comcode pages and general Comcode usage.
• Block cache: Caches blocks based on their parameters, minimizing execution.
• Theme image cache: Prevents redundant searches for theme images.
• Values caches: Stores calculated values like member post counts.

• Check Email Logs: View the email log (Admin Zone > Audit > E-mail queue/log) to see what notifications have been sent.
• Use the SU Feature: Impersonate a member using the SU feature (described in the "Testing access and privileges" tutorial) to view their notification settings and confirm they are set up correctly.
• Enable Carbon-copy Email: Configure a "Carbon-copy e-mail address" in the configuration settings to receive copies of all outgoing emails, including notifications. This helps you monitor email delivery.
• Verify System Scheduler: Ensure the system scheduler is configured correctly if members are not receiving digest emails.
• Check Digest Settings: Confirm that "Enable digest notifications" is enabled in the Messages configuration settings.
• Review "Safety listing limit": If a notification has too many categories, members might not see the full selection tree. Adjust the "Safety listing limit" in the configuration settings if necessary.

• Notification Lock-down: You can force members to receive or prevent them from receiving certain notifications (Admin Zone > Setup > Notification lock-down). This allows you to enforce specific notification policies and manage email volume.

• Friend Requests: Notifications for new friend requests.

• Private Topics: Notifications delivered as private forum topics.
• SMS: Notifications sent as text messages (requires configuration and incurs costs).
• Web Notifications: Real-time alerts displayed within the Composr interface.

Multiple display modes: Display the contents of categories using tables, boxes, or lists.

Powerful structure: Each catalogue contains categories which contain entries. Catalogues can have a tree structure of categories and/or work from an index.
