I didn't have to register, I just input F/L name and email and it sent me on through. I think they just have the email field to eliminate duplicate votes on behalf of bots or people who just create gmails at will. Likewise with the IP pickups and the .001 BTC donation. Haha, damn they really thought this one through!

Upon reading their last voting poll, it looked like LottoCoin tried to fake about 300 votes with bots, so it seems they're doing things much differently this time around.
