Just to make everything a bit clearer, here are some rules for the contest:

Each member may only make one attempt at a guess per day; these must be posted on the profile page as before, simply listing the image number and the name of the artist. Contributing artists may not comment!! If no one seems close to getting all the artists correct, I may start to give assistance simply by letting each entrant know how many of their guesses are correct. These clues will be posted on the profile page, so everyone will benefit from them.

If anyone else thinks there needs to be any more rules/guidelines, feel free to post your suggestion; this is a "work in progress"...
