First, the claiming post will contain all the story summaries, under a cut, and without the writers' names. The post will be screened, so your friendly mods will be the only ones to see all comments.
Each artist should comment to the post, and include your first, second, third, and fourth choices for story claims. (If you could also confirm whether you can work on two stories, that would be great. We have 10 artists, and 22 stories in need of art, so we will be very much depending on your generosity.)
The mods will do a first pass through the list, starting with the first comment, and assign each artist their first story. If your first choice has already been chosen, you will be assigned your second pick.
Once all artists have had a chance to make a claim, and have been assigned their first story, the mods will do a second pass through the claims, and assign each artist who has agreed to work on a second story their second pick, based on their remaining choices. (It may take a day or two for us to get to this stage, as at least one of our artists might not be online on July 5.)
We chose this method to ensure:
ETA: Note that once you have claimed a story, you'll be getting the rough draft of that story, so you don't have to work just from the summary.
Let us know if you have any questions. And thanks once again to our artists for volunteering your time and talent.
