Everything he said in dodgeball was hilarious!
To post an avatar, click on the profile button
on the top of the screen (by FAQ, Search, etc.). Scroll down to Avatar Control Panel
. You can choose one from the gallery, or link one from another site (for example, if you host images on photobucket, imageshack, etc.). If you get one from the gallery, select the little circle of the avatar you want and click "Select Avatar", and then Submit. If you want to use one from a different site, just put the link from the avatar in the "Link to off-site Avatar:". Hope that helps.
