Yo!!
There's 2 ways to look up a deviant. First is simply putting their name into the addy bar. For instance, I'm leperdoctor- so you just put my name before the site name.

The second way...doesn't work anymore since they changed crap. Again. <.< If you know where the dude / dudette is from, use a geographic search. I dunno how to do that, but that's what I was just told. <.< The first way is easier...
