Domain User Registration Limit

Domain User Registration Limit provides configurable user limits for Drupal sites using the Domain and Domain Access modules.

The module allows administrators to define a maximum number of active users for each Domain + Role combination and enforces those limits across user registration, administrative user creation, role assignment, domain assignment, and programmatic user saves.

Features

• Configure user limits for specific Domain + Role combinations.
• Display current users, maximum limit, remaining capacity, usage percentage, and status.
• Support unlimited and disabled limit configurations.
• Block user creation when the configured limit has been reached.
• Enforce limits for both administrators and public registration.
• Send optional email notifications when limits are reached.
