I agree with Vorlx.

What about using the point system for tournament entries.

So for say, a screen shot contest, you give away prizes like GHII. People have to pay a entry fee point wise. It woulld be fairly expensive. To get the, say 1.5k points?, they have to post and refer people. You could set the first 30 post to make them 50 points instead of however much it is.

Or something. idk. grammer is fo gays.
