Sweet giveaway! Bet you're drawing a lot of traffic :P I'd love to enter as well, so please throw my name into your digital hat!
One question - I know it's one entry per person, but how do you determine 'duplicates'? For instance, I'd love to have other family members who play enter, but they're on the same network, and the logged IP will be similar, if not identical. But if it's just looking at account names, then you can have a lot of people just creating new accounts... which even I could be accused of doing, were I to tell family members to enter!
Real dilemma - any input? :)
