How do I give a user control over a specific usergroup?
 

I have a private forum on my board that requires being apart of a specific usergroup. I don't want to manage this and instead let another user do this. How do I give them permission to add/remove people from this usergroup?

Put them in a usergroup that gives them access to the admincp and then set Administrator Permissions how you want them for that user (to have access to edit users).

How do I give a usergroup access to the adminacp?

--------------- Added [DATE]1295915504[/DATE] at [TIME]1295915504[/TIME] ---------------

In the end, I want to grant them access to add people to a specific usergroup. That usergroup has access to a forum that no one else does. I want to do the same with a calendar.

Make the UserGroup joinable, and then on the UserGroup page, "Add Leader" the right username. :>
