This might be a dumb idea, but would it be cool if most of the characters were PXR members as Pokemon? Like in the PXR Adventures stories? That way there wouldn't have to be a limit to a few characters since we all already know each other. And I think people like seeing things starring themselves, so they might be more interested in reading and participating. And of course, even if we did this, it would probably still be a good idea to have a main character not based on a member. Just a thought :)

This looks really cool and I look forward to seeing how it goes! :D
