Joshua Eichorn has posted the official contest rules for the WebThumb Contest announced a short while back.

The contest runs until November 30th, and the top 5 submitters will all win upgraded WebThumb accounts. The top submitter will also win a copy of my book, Understanding AJAX.

Since previously, all that was required was a comment on this blog entry, people who've posted there need to listen up - an official submission needs to be made. Check out this page for the complete rules and all of the information you need to include in the submission email.
