When the deadline passes, tomahawk (the guy running this series of competitions) will package all the files up into a zip folder and post a link so we can download all the tracks and rate them. All you'll see in the folder is the tracks and their names, there'll be no indication which user sent which track (tomahawk will keep track of this, don't worry).
Then everyone can rate the tracks from 1 to 5 (1=crap, 5=amazing) and email or PM tomahawk their scores for all the tracks. The judges (tomahawk, Jer and myself for this round of the competition) will do something similar, however we'll score the tracks on a more detailed range of categories that will be totalled to give an overall score.
All your ratings, plus the judges ratings, are then all averaged together and the winner is the one with the most points!
Hopefully that makes sense!
