After searching and searching I couldn't find what I wanted. I checked the FAQ, but still. I have no answer.
I made forum. I created categories, forums, sub-forums, topics everything. My question is: How can I set Moderators/Administrators to administrate this forum?
Like:
Forum Rules
[here goes the description]
Moderator: Administrators, Moderators

Display>Structure & hierarchy
Display forum moderators :Yes
Save.

It is already set to "YES", but that's not my question. My question is how to set a member group as a moderator of this part of the forum.

Users & groups>Group administration
Click on Administrator group,
Permissions tab
For any specific forum, check Is Moderator.
Check Is Moderator for all the forums.
Administrator group will now appear.

Repeat the same procedure for Moderator group.

Alright. It's done! Thank you!
