[Edit] I've also changed the avatar picture size to 100x100 pixels. People who've already set avatars might need to re-set them to see the larger sizes. 80x80 seemed very small to me.
My professor is looking mighty squat as a result.
Why didn't you give us the option to give a URL to where our avatar is hosted, instead of hosting them all yourself?
