Ah yeah, you need to make a character in game first before you could vote.
When you vote, it rewards you with Scrub Tears. Its a type of currency ingame where you can buy some pretty good stuff like mapmove scrolls, costumes, mounts etc.
But yeah you need a character made first and connected to your forum...before you can vote XD
Not sure if this was it but, you can go to your
http://noscrubs.net/community/profile/edit after the game downloads and you made a character with an In-game-name.
