1) I can add other people as mods if you want to. That should be possible since it's a forum.
2) I don't know where the forums will be put yet. Maybe in the chill out lounge or their own category. Maybe you can suggest something better.
3) I'm not sure how much you can do if the forums are connected to usergroups. I still need to test that.
4) I would have to do it. You can just tell me and I will as long as there are not too many.
I really hope this hack will be useful for you
