I'm not, strictly speaking. We treat it as a community-owned forum so I try to treat lightly, though I have taken more control over some areas of late, mostly because no one was showing any interest otherwise. I wish we had gone the route of the original admin team owning it. Though that would have had problems, too, since one of us (the one who originally installed Xenforo) left in a huff a while ago.
This member only dropped the one racist remark that I've seen and, to be honest, it was so obscure that I think I only picked up on it because it could be applied to my wife as well. The original ban, while brief, did seem to result in no further serious offences though I'll be the first to confess that I do not read everything he posts anymore. I have better uses for my time and brain cells.
