OK, so I just haven’t bothered to find out until now. Where do you get them & how do I set one up?
Up at the very top of the page, there’s an orange icon that says “User CP”. Click that.
When you get to the User CP, you will see a column to the left under “Control Panel”. The fifth option down is “Edit Avatar”. This is the destination.
From there, you need to make, or find an avatar that you find fitting. You must abide by the size requirements, and you can upload an already saved avatar from your own computer, or you can find another one on the web to upload.
