You can change your display name, avatar color, and add a profile photo. Here's how to do those things:
- Click on your avatar (the colored dot) and then click on the profile icon that appears. The default name you're given is a random mashup pulled from a list of adjectives and nouns.
- Here you can change your display name, color, and upload a profile picture from your local file system. Your avatar color will be automatically generated from the profile picture that you upload.
