right basically the mods set up a thread
a poster posts in the thread
then a mod uses the random number generator to get a number from 0-100
depending on that number the poster can get a prize (points, the ability to change someones username, or a chance to ban another member for a selected period of time) or a forfeit (ban changed username (mods choice) etc)
the mod that used the rng would edit the posters post to notify them of what they had won
any clearer?
its that simple
it actually sounds like it might be alot of fun
