Hmm... As much as I like making custom races, I don't think that Techtree contests are necessarily a success.
On the one hand, if you have
no custom content or triggers, everyone can join and things feel more fair. But then they all look rather similar, somewhat boring; only the really good people can make good usage of the hidden models/icons/etc.
On the other hand, if you allow custom stuff, the "elitists" join and overpower a boring race scheme with amazing custom models/sfx/etc, and things are less fair for others.
Also, I have some semi-completed races; I'd hate to have to redo all the work, especially with a deadline. I'm
pretty sure that they wouldn't allow already half-completed races in the contest :/

@Darkwing: So you have a Troll race too, eh? Keep talking...
