The art contract idea/project would have to be the best of the three not that I have anything big against the other two. It's just that it'd be nice to search artist that way for art and it seems like it could be really convenient. The forum titles could be fun at first too but that'd just kinda fade. I'd get bored of it pretty fast and slowly make it just one of those things that's just there if that makes sense. I'm not sure I'd really go for the war thing at all, not really my thing kinda seems like a waste of time. Though it could be fun, can't hate it before I've tried it. I say go for it, they're all nice ideas/concepts. As long as you dont stop your current projects for them which you said you weren't going to; I approve.
