We have an avatar collection that you can choose from. After you have a certain number of posts (10, I think), you'll also be able to upload an avatar of your own.

To access the page where you select or upload an avatar:

1. Locate the My Profile link at the upper left of any forums page.


Click on it and it'll take you to the User Control Panel page.

2. In the left column, under Settings & Options, find the Edit Avatar link and click on it (see attached picture).
