Features

Discourse communities often need to automate group memberships based on conditions like badge ownership or existing group memberships.

Common use cases include:

  • Users not in the ‘subscribers’ group

  • Users not banned from posting in Marketplace

  • Users at TL0 or TL1, but not TL2

  • Users who have completed the new user tutorial or have been members for over a year

  • Users belonging to client_1, client_2, or client_3 and are not an intern

Previously, solving this required custom scripts that periodically synchronized groups. The Dynamic Groups plugin eliminates that need.

This plugin introduces a boolean expression field to group settings, allowing administrators to define rules that dynamically determine group membership.

Examples:

  • users who are not in the ‘subscribers’ group
    trust_level_0 AND NOT subscribers

  • users who are not banned from posting in Marketplace
    trust_level_2 AND NOT banned_users

  • users who are on TL0 or TL1 but not on TL2
    trust_level_0 AND NOT trust_level_2

  • users who completed the new user tutorial or are member for over a year
    badge:certified OR badge:anniversary

  • users who belong to client 1, 2 or 3 and are not an intern
    (client_1 OR client_2 OR client_3) AND NOT interns

Configuration

Once the plugin is installed and enabled, a new tab will appear in the group admin interface:

When you enter or update the boolean expression, the system will take a few moments to populate the group with matching users. From that point on, group membership will be automatically updated as user status changes.

Important:
When a rule is defined, the group is marked as automatic, disabling manual member changes. To revert the group to manual management, simply clear the expression field. The existing members will remain, and you’ll regain manual control.
