I've only ever written for two fandoms outside of this one, and that would be
Doctor Who and a German show called
Verliebt in Berlin.
You can find my
Doctor Who stuff at
http://www.whofic.com/viewuser.php?uid=681 (same warning as Wendy's btw, as I did write some slash scenes as well)
My
Verliebt in Berlin stories can all be found at
http://b-style.xooit.fr/f14-Fanfictions.htm under the name 'Destiny'. Beware that I've been writing solely in French in that fandom.
