HiH Clubs

So I've fallen in love with this tumblr: http://livesandliesofwizards.tumblr.com/ and I think, best way to kill two birds with one stone, maybe it can be a smarmy activity (the winners of whom can then be posted to the Tumblr >.>) -- given, say, three unique/artsy/vintage picture prompts, members write a drabble about a little-known character or a little-discussed aspect of the HP universe, and then they're put up for voting? And instead of the 50/40/30 for placement rule, people can get a 40/40/40 so one winner can be picked per prompt (but a person can only submit one/place once, either way)?
