My feelings won't be hurt (okay, they sort of will), but feel free to cross-post to here.

We were planning to launch our own contest to promote the site (when it's polished and stuff), but that doesn't look like the best idea, necessarily, any more.

I have a couple other ideas that I'll throw around with other members, but for now, don't feel pressured not to enter just because we may or may not be competitors.

Various educational institutions nearby me leave doors unlocked for some computers and studios. Groups are allowed; if anyone wants to team up with me, I can map and do sound/music: I won't be able to test or even play the finished map unless I get a computer, though.

Definitely. Will I win? No. But I'll enter, I haven't mapped for Portal 2 in a while.

You forgot to link to the contest/rules page:
