This would be massively easier to read if it was aligned left than centre. Massive paragraphs are a pain to read like this.
EDIT Okay, I've read it now, and although it is well thought out, in practice I doubt it will make any difference. People post in RPGs because they're fun, not because they're getting any kind of reward out of it.
Also, this whole thing might become incredibly bureaucratic and require a lot of legwork to get working, even if people did start chasing coins and stars. I'll see if anyone would participate in such a scheme before I officially throw my support behind it. If a lot of members do participate in it, it could work out very well. If only a minority participate, I can't see it working out.
