A huge thanks to everyone who participated, I had a lot of fun with this. It was my first time modding a fic challenge, and so I appreciate your patience with the changing schedules and everything. I'll be putting up a poll for feedback, and I'm especially interested in feedback from people who signed up but weren't able to finish, so if that's you then please keep an eye out for it. The poll will also be my attempt to gauge interest in a second round, since there seemed to be so much interest in the challenge initially, I want to try and give as many of you guys a chance to finish and post as possible. :)
If you have any final questions or comments, leave 'em here.
