Regretfully there has been a significant amount of spam on the site. As such, a number of precautionary measures have been taken. If you are a good-faith user and any of this has adversely affected you, I apologize.
1. A number of users who have signed up until now have been deleted.
2. Users ability to form member groups is unavailable until further notice.
3. I may try charging all users as a safety precaution.
