What is an avatar anyway? This is the small image that appears under your name on all of your posts. To get one setup for yourself, do the following:
1. Click on "My Settings" in the menu bar above and select "Edit Profile"
2. On the profile page that loads there will be a menu along the left side of the page. Find "Edit Avatar" and click that.
3. The screen that loads shows your current avatar and ways to pick one from the list of pre-loaded avatars or you can even load one from your computer or from a website address (url).
For example, if you wanted to use one of the avatars found on the pages below, you'd get the url from the input boxes found on those pages and copy (right click, select copy) and paste (right click, select paste) it into Option 1 of the custom avatar area.
