I had stuck with my original/default gravitar thinking I may put my face up if I ever hit 10k as that seems to be the done thing round here. Anyway I thought I would change it when everyone did the anti SOPA/PIPA thing but I couldn't suss out how to revert to the original so it's stuck ever since.

Am I being a retard or can it not be reverted?
