This module changes your forum administration page to allow you to set forums private. You can control what user roles can view, edit, delete, and post to each forum. You can also give each forum a list of users who have administrative access on that forum (AKA moderators).
This module requires the ACL module in order to function. The D7 version also requires the Chain Menu Access API2.x module.
Forum Access for D7 is compatible with the core Forum module, Advanced Forum, and Content Access, Domain Access as well as all other well-behaved node access modules.
