Harry Potter Fic Question

I just finished re-reading the entire HP series.  (There are certain books I've read many times - 1 and 3, in particular.  But this is the first time I picked up book 1 and read straight through to book 7 without reading anything else, and only my second read of Books 5 and 7.  I am still not a huge fan of 5 because I hate Delores Umbridge with the same ferocity that I hate, say...George W. Bush and Rick Santorum).

Anyway, I have never been really interested in Harry Potter fic before, but now I'm curious.  Anybody on my flist have any HP fics or fic communities they can rec?
