Sign ups now re-opened (were temporarily closed)

[fadmods]

Sign ups will be temporarily closed (hopefully for just a few minutes) to fix a lingering tag set issue.

If you are currently working on a sign up, please do NOT hit submit until this message has been updated. Thanks!

Sign ups are now re-opened; we have removed a single tag that had slipped through for an "&" rather than "/" ship. Any participants directly affected have been contacted by email.
