I found myself an avatar recently Musicman - this eagle. My first effort was a photo I took earlier this year, but Buechico pointed out it was too small to be seen. After being despondent for a month I changed the picture to this eagle I found on a Clipart CD. It's the only picture I found that I liked and was large enough to be visible.
I'm no computer whizz. Believe me, if I had no real problem setting up an avatar, it's not that difficult! Just remember to make it something discernable as it appears quite small as an avatar..
