Not a fan of the background on the avatar.
I may have to rethink this or remove it.
Mine also came across with a nasty blue background. I found a bigger version (now 200x200 is recommended) and uploaded it as a replacement. I had to delete my existing avatar before the new one would upload.
Before I deleted my existing avatar, the upload seemed to stall for me too. After deleting my avatar, the upload was effectively instantaneous. Maybe I was just lucky...How long did you have to wait? Mine hangs. It stays on "Waiting for forums.anandtech.com" and the status bar looks like it's trying to upload it, but then nothing happens.
I was ahead of the curve in having a circular avatar already
