If you mean how to load avatars on the forum, then that's
easy. At the top of the page there's an option called "User
Control Panel", click on it. Once you get to that page, on
the left there should be a few options. Click on "Profile".
There! Just look at the left again and click on the "Avatar"
option. Then you should be able to load an image from a file
or put a link.
