I say this isn't needed now, any non community member who wants to suggest an idea, simply he Pm's an any JCM+ to suggest it for him.
That's the requirements for JCM, so they can just apply. If they yet manage to fail writing a proper application for JCM, then they wouldn't meet the standards to take part in constructive discussions within the developement board..
much players downvote the the CM apply for trolling so they maybe will be denied.
