Homestuck will always own a part of me, even if it's not even really that good anymore. If you need a co-GM I'd be happy to help you plot stuff out, and judging as you said you have no ideas I could give you the general rundowns of RPs I've been in before.

EDIT: And you know what, if this [i]doesn't[/i] get off the ground, I might just do something Homestuck (or at least bumming off of it) considering how much interest has been shown.
