Alt to Fet
There has been much discussion on Fetlife over censorship on the site lately. There is however an alternative site with all the modules and more available on fet with easy navigation based on "Facebook". The site has plenty of privacy settings that will satisfy every member.
The site has a great events section where organizers can pimp events with pics and members can add events to google calander so they are reminded of events posted well in advance. Recuring events can also be posted.
