That's a bit hard as I haven't been so constantly on-line over the last year. However, here are goes -
1) Seasonal Spuffy ...
Run over on Dreamwidth, now, but cross-posted to LiveJournal. This is run for the love of Spuffy ... ie, Spike & Buffy from BtVS ... point to my icon! The first OTP that made me discover the life of fan-fiction, and LiveJournal.
2) The Dresden Files
Now I hate to say this one, as I really do not like FaceBook ... but, I will go there to see what is being posted. It is a closed group, but just a couple of questions to answer, and you can get to "chat" with other Dresden Files (by Jim Butcher) lovers.
3) Photo Scavenger ...
photo_scavengerThis is a site over on LiveJournal, and again a closed group (however all you need to do is ask, and if you are a real person, you get to join). The site consists of a challenge per week to take a photo (for example this weeks challenge is "evening")
