The Wotch --- PG TF Webcomic.

Gammatelier --- Gamera's site, plenty of bodymod and other unusual things.

Naga's Den --- A very good transformation artist, Naga offers everything from lamps to centaurs. Arms not required.

Monstergirl --- Not strictly TF, but monstergirls are close. A japanese picture board that welcomes foreign vistors, try to be polite.

P-Spies --- Any sort of body modication counts as tf, or at least I think so. Pregnant spygirls, for instance, are just fine.
