I woukd be certainly interested in participating in your iniciative. I think I woukd fit in the mechanics / storytelling slots, so if you have no inconvenient, you can count me in.
I was trying to create my own system long ago, but it's a hell of a job for a single person and I didn't get far. I would like a SciFi setting, but I'm interested in about anything related to RPGs.
I'll keep an eye on the thread.
Edit: once I get to my computer I'll elaborate more my application, I'm with my mobile phone now and writing is a pain in the posterior.
