Also giving them out, just PM me your email address. And I have a tip, when you first sign on you have a game, where you catch different sized PTZ. In order to give yourselves better chances, you can slow the game down by Googling 'Cheat Engine', downloading it, installing, launching, then click the system button in the top left, choose your browser from this process list, and then click 'Use Speedhack', set it to 0.1, and then click apply. Now you can play the game ten times slower, and have more chances to get points.
Hope that helps.
I'll be on here pretty much all day, and so the invites should be quick.
