It won't let me change my avatar for some odd reason.
Are you sure you're entering the URL correctly? :P
I copied and pasted it, so yes, and the url is showing, but the same old avatar is still there.
Remember not to put in IMG tags. Other than that, it should be fine.
you don't use img tags for the avatar
I would tell you what to do, but even I don't know how you're screwing this one up...
