By the way, if you delete the MTV website cookie off your computer, then you'll be able to vote more than once a day and the website won't be able to tell you've already voted.
Just search for 'mtv' in your Windows folder and find a file named like:
your_name@mtv.txt
Delete this once a day before you vote.
Then after you've voted, hit the back button on your broswer and hit submit again.
Do as many times as you wish! And I think that'll prevent the website decting you've already voted.
