To change your avatar, you need to be on the Learning home (the homepage for Learners!). If your default home page is Parent home or Coach Dashboard, follow the link to find instructions for opening your Learning home.
Once you are on this page, click the avatar in the upper left. This will open the avatar selection window.
Navigate the selection window by clicking the circles on either side of the current avatar, or click the All avatars button at the top left, and use the scrollbar. The currently selected avatar will show up with a gray background. Click Save to keep the avatar. If you do not see the Save button, try scrolling down or zooming out from your web page.
The avatar you select will now be shown in your bio!
