There have been many posts here on DO that keep telling people to fill in all the slots on the VH-1 site in order for your vote to count...

You DO NOT have to fill all 20 slots in..just drag and drop Daughtry into the #1 slot..you can vote for whoever you like...1 or all 20...your vote will be counted!
