Since the Yahoo! groups are now ready and we have an initial head count and won't need to have multiple main groups, please sign up directly at the group sites!
When you sign up, please include your Ravelry ID, name, and a little bit about yourself in the comments. Also, if you're a beginner, please mention that as well.
Early Group (for those wanting the clues on Thursdays)
Surprise Group (the no-spoilers group)
