updated 3/3/10. We're back on open membership. Just join.
Apparently there's been some complaints about the only-invites method. Please don't take this personally; we were only cleaning up the community (which took a long time) and we figured the members in the community whose journals were inactive weren't active anymore. For the most part, we were wrong.
You're now able to rejoin if we accidentally removed you from the community (or if you're new, you can just join!) Sorry for any inconvenience.
