In your own space, promote three communities, challenges, blogs, pages, Twitters, Tumblrs or platforms and explain why you love them.
hpsapphicappeal is currently my absolute favourite fandom place. It's a femmeslash comm, but it's more than just that. It has, to date, hosted a totally fabulous fest, plus the Bertie Bott's 100 flavours table challenge, plus Sapphic Stockings over Christmas. And you can always post femmeslash fanworks there outside of fest times. It's fabulous! I love the community lots, and I'm looking forward to seeing more events happening there in the new year (Femmeslash February, anyone?)
The Harry Potter Fanfiction Challenges Forum. Okay, yes, I know, I know, ff.net *gasp*. Whatever. This forum is awesome. The thing that's great about it is that it's so self-directed. There are mods (I'm one of them), but all the challenges are created by ordinary members. Unlike the fest structure that's popular on LJ, where every individual fest is a big ordeal involving anonymity and multiple steps, the challenges hosted on HPFC are usually designed to be low-stress, with a focus on inspiring writers rather than just creating works. Because anyone can create a challenge at any time, there's a near-100 percent chance that, at any given time, there will be a challenge running that interests/inspires you. The forum also hosts various awards and competitions, and amazingly, I have never once seen any drama or rage about people winning things, because there really is a feeling there that as long as everyone is writing and having fun, everyone is a winner! It's idyllic, I must say.
@FriNightWrites (aka #writeclub). Not really a fandom thing, but a great twitter to follow if (like me) you write, and if (like me) you have trouble motivating yourself. It's basically a weekly set of word wars that take place on Fridays, in the afternoon/evening. As an aside, I have totally failed to get into twitter as a fandom platform. Does anyone reading this use it for primarily fandom things? If so, please tell me about what your experience with it has been!
