At this point you'll find a lot of Doctor Who (my main fandom at the moment), a decent amount of Rent, some Feeling Electric and a decent amount of House as well. Plus there are other things scattered in between but those would be the four big ones.
Comments area always encouraged as is especially constructive criticism of any kind.
And last but not least, a disclaimer! If you're wondering about ownership And other legal facts, Just repeat to yourself "It's just a fic, I should really just relax"
