URGENT: You can legally vote more than once.

Voting Rules
Polls close January 12, 2009.
You may vote once every 24 hours in each poll.
After voting in an individual poll you will be locked out from voting again in that poll (on the computer you voted from) for 24 hours.
Each poll has its own separate 24 hour lockout control. Voting in, for example, Best Blog will not lock you out of voting in other categories
