I'll willingly host a contest~! I do it all the time so its not really a hassle and I'm good a keeping shite on schedule.
I'd just need to know whether you guys like prizes and stuff, and if so what type of stuff? Also, would need help judging (since I'm not exactly the all knowing mapping extrodinary, and I would probably be judging on whether it looks good and plays nicely), but that would be easy I'd get Scotch to help me and anyone else that would like to assist but not compete.
Hell, I'd be willing to organise monthly contests if you guys were interested. XD
