Moderator Permissions Question
 

I have a small job I'd like to give someone on the forum but I don't want them to have full moderator permissions. All I'd like them to be able to do is edit posts in a certain forum area. I was hoping to create a new usergroup based on Registered User then tweak it to allow them to edit posts in that one forum. Can't seem to figure out how to do it. Any suggestions? Thanks.
