The problem is that each time you logout, the counter of your vote dissapears and you can vote once again.
I noticed this on one trip, because using the hotel PC, I had to log out each time I used the computer to prevent any spam by any other person who use the computer.
This never happens on my PC because I never logout, being almost the only user (Neither my girlfriend or my family when visisting me, care about Prog').
I don't give a damn about polls, but maybe there's a solution because if some people take their time to create a poll, the least we can do is to make it the more reliable possible.
