Now I am not real good at remembering myself how to do it but Go to User CP on the left hand side directly above where you started posting here. Click on User CP and go down to setting and where it says Avatar (or change Avatar) click there and follow the instructions as you go. There is one area where it says change or add file (I am doing this with my very short memory) that you might have to enlarge the screen to find the upload option. Once you click on this you have done it and can see your avatar in the little box.
Now if I did this wrong will some one jump in and help her along.
Thanks for the compliment on my quilt.
