Namesnipe Simulator

Randomly chooses either a 4 character string (all letters) or a 4 character string with an underscore, checks if it is taken, and if it isn't it tries to filter it, and if it can't, it'll show it to you as an available username. It uses 2 player servers since any more than 2 players and it will be really slow for some reason. Feel free to copy the source to this game, I don't need credit although I'd prefer if you didn't charge for any features provided in this game :)
