A number of people have had trouble adding an avatar in these forums. If you'd like one but don't know how to put one on, here's how. First you'll need the pic for it saved on your own computer.

Go to your control panel from the User CP link near the top left of most (all?) pages.

Choose Edit Avatar from the menu on the left.

Check the radio button in the Custom Avatar section.

Choose Browse in Option 2 and select your avatar from your computer.

Click the Save Changes button at the bottom.

Your avatar should then be showing.
