Ok at the top, right of the page is your name. Below that is Private Messages: Click on this. On the next page, on the left, there is a column of options, you should see under Settings and Options "Edit Avatar". Click on this then follow the directions. I'll be looking for your avatar.
Or start by clicking USER CP upper blue line on left. Then Edit Avatar. Find a photo in your private albums and go from there. Looks complicated but most of us did it so it can't be too difficullt. I'm with fannie waiting to se your avatar.
