Voting is done by mail, sent to the four "judges" (really vote counters).
First, decide which two users who entered the contest you want to give your vote.
Second, figure out which "judge" (vote counter) will receive your votes. See the
link for details.
Third, go to that vote counter's profile page. In your case, since your username starts with Z, this is
link.
Lastly, send a message to the correct vote counter with your votes. That means click the link labeled "Send a Message" on the vote counter's profile page.
The message should have "FGT <year> voting" as the subject, and should contain the names of the two user-contestants you have selected as the most talented.
