I used to use ogame's and archlord's forums, I don't play those anymore, tho, so there is no need for me to use them.
As for other moderation, I'm admin at toribash.pl, I should probably say I was, since it's pretty much dead; I've created and moderated 5 to 6 clan forums in my ogame period (2005-2009). Hm, that's all what I can remember.
