Well, you may also edit the Moderator usergroup. And, when you add a Moderator to a forum, you get a permissions screen also. It kinda depends on what you are trying to change.
I dont have forum specific moderators. I checked out the Moderator usergroup but it doesnt give you all the options like when you go the show all moderators way.
Is there an option of setting the standard permissions for all moderators instead of going to show all mods and editing them one by one?
