I think I've finally figured out the camera and computer, now how do you post a picture for your avitar?? Also I see some people use emoji's (sp?), how is that done?? Bear with me as I'm 76. Paul in CT
click on your "blank" avatar, where it says "profile page". Then click on the avatar itself. See if you find a place to upload an image file. Make sure the image is the right size first, it should be about 200x200 pixels. Then upload it. If you have trouble, find a youngster to help you.
The quick route is to Click on the profile image (green arrow) click on Avatar (yellow arrow) then click on choose file on the avatar editor (blue arrow in second image)
