Activation Reminder & User Purger
For larger forums, managing membership can be a daunting task. With Activation Reminder, automatically send an email to users who have registered but never activated their account after a set number of days. If they still don’t activate their account, utilize User Purger to clear them out automatically after a specific time, too!
