I hadn't really noticed it but now that you mention it perhaps they are bigger.....and what? You don't want to see a big ol' donkey every time I post? *lol* At least he's got a nice jacket so as to maintain his professional image
I usually have a hard time discerning what people's avatars actually are because they are so small. Some of them look like they are really cool but I can't be sure. If the size has changed by double it would be good to know so folks can make sure their avatar doesn't look like 8 bit graphics.
