I think I'm going to stick my foot out here and say that I am not willing to make this a skill based competition on gaming performance. I know Mitch's equations were very clever, but to be honest, that's too complicated.

You guys have got to remember that this giveaway is also to try and attract new members, whilst also rewarding those who are much more long-standing. This leads me to think that it HAS to be forum based, since this is where most of us go the most.

To segregate new and old members, we could make it so that the top prize can only be won by a member with more than 50 posts and perhaps make the competition easier to those who have been in ATK longer.

However, by it's definition, a competition still requires skill (of some sort). This is why I think that only the top prize is skill based, but all of the <£20 prizes are more randomly drawn, but you must do SOMETHING to enter. For entry therefore, perhaps a screenshot that sums up community gameplay, or something like that? Everyone has a chance, but the best one wins the top prize. No massive photoshopping will be allowed (sorry vox ).
