Help me make a filter!

[heidi8]

Now that I can have an insane number of people on my flist, I want to have a filter that's a mostly-fic-reading filter - communities, writing journals, newsletters and people who post fics on their LJs.

I want to add any of you who write & post fics to it - I think I have a good idea of who's writing at present, but just to make sure...

Poll

Anything in Harry Potter, Supernatural, Heroes, Doctor Who/Torchwood and crossovers regarding same would be greatly appreciated!
