This page contains general information about you.
You can change/modify/update any information you wish. You can also change your avatar if you wish.
For the time being, you cannot upload your avatar. What you can do is provide a URL to your image or you can register an account with https://en.gravatar.com/ and create/upload a picture there. Once that is done, link the email that you have registered with on the Gravatar page to the Simitless system. And, voila! You’re done!
You can do either of these once you click the “Change Avatar” button.
