Go to www.Gravatar.com upload one and rodo use the same e-mail so TPT can copy your avatar. Make a new TPT account and a new e-mail you can remember with.
@rodo(View Post) The best thing to do, as jacob1 said, is to message Simon about it. He'll have the database containing all the emails of registered members. Then all you need to do is make a gravatar account with that email and select an image to use. It normally takes about 10 minutes for the image to render on your tpt account, so don't be alarmed if it doesn't work immediately. Of course, this is if you manage to find your email.
