My profile: http://www.fanfiction.net/~captainemily
Also, I have a Delicious page for fic recs, many of which are crossovers. http://www.delicious.com/captain_emily11202
While I do post almost all of my fics to LJ, I recommend reading it on FF.Net. I don't post multi-chaptered stuff to my LJ until it's finished, and when I periodically edit and/or change things, I rarely take the time to copy the new stuff to LJ. It takes way too much time to update the format.
