There isn't ever going to be another 50th Anniversary of Doctor Who, so this is a place where fans of the greatest television show of all time can come together to mark that occasion and celebrate it together. This comm is dedicated to the idea of Who At Fifty, a place for people to post about the anniversary itself, about 50th anniversary-related media and news, meta about what Who means to them, details of RL events they're participating in or organising to celebrate, or just general japery.
But the main thing is going to be monthly ficathons, one a month for the duration of the anniversary year and covering all of the Doctors to date and various supplementary prompts intended to cover as much of the fifty-year phenomenon that is Who as possible. I wouldn't expect anybody to sign up in advance to writing something new every month; it'll be something for people to dip into and out of, and hopefully some good fanfic will come out of it. Fan art, fan vids, fan mixes and other forms of creativity are all welcome and you can post all of this sort of stuff to the comm any time you like, it doesn't have to be part of one of the formal ficathons.
So, I hope as many Who fans as possible, of whatever age and duration, fans of whatever era in the history of the show and its many spinoffs and associated media, join this comm. And maybe together we can make 2013 a year to remember!
