I signed up, but I did want to make a note, especially about Doctor Who, because it could come into the same problems as your SG1/SGA crossover issue from last year. I am primarily a classic Doctor Who writer. (The older series.) I have written several new school Doctor Who fics, but not, I think five over 500 words. I have, however, written many, many classic Who fics over 500 words and therefore DO qualify according to your rules. However, if someone who is only familiar with the 9th and/or 10th Doctor signs up and gets me, they may be very put out, since I have very few stories featuring just the new Doctors. In the future you may want to split Doctor Who into classic/new series to avoid this potential problem.
