Make sure to submit ratings for at least 10 artists. Jurors that only submit a few ratings are ignored.
If you rate someone twice, the new rating will replace the old one. If you submit a blank rating, the server will remove your rating for that artist.
If you have work in the show or know an artist that does, feel free to participate in the selection process. Keep in mind that the server is designed to identify abusive voting patterns, so vote everyone fairly.
