At this point you can either choose another TBS avatar or add your own custom avatar. To use a custom avatar, make sure that "use custom avatar" is checked "yes".
If your custom avatar is located on a web server, you may link to that avatar by typing in the URL of the file (i.e. http://www.starwars.com/avatars/youravatarhere.jpg).
If your custom avatar is located on your computer, you may upload it to the TBS server by clicking on the "browse" button and locating it on your computer.
NOTE: Avatars can be no larger than 70x70 pixels.
If you have any questions, post them here. Thanks.
