I don't think you fail at relaxing at all. And this is something that interests you, so it wouldn't be busywork you don't care about that's just keeping you from being bored, or anything like that.

Maybe you could check with SDW and see how much effort it actually takes, because it seems as though you'd only really be hosting, and letting everyone do their thing in your space. And if some unacceptable comments should happen to drop and you don't see them right away, I'm sure someone will let you know, so you can delete them (I'd totally do that, too, and let everyone know up front it's not an open forum to be an anonymous douche to people you hate, and douchy comments won't be tolerated).
