Hmm... here's an alternative:
How about you join my group, give me some of your many ideas, and see if they'd improve some of our many ideas? Of course, programming skills, etc are appreciated... but we could always use an extra designer. Most of the games in the world suck simply because they were poorly designed.
For application, please send me the best idea you have...
