Your name, the cartoon you, light or dark, and your flexpert page.
Your profile is at flexos.me/welcome/you: from the account menu on the projects page, or the row on a phone's More sheet. It is your name, your picture, how the workspace looks, and your account.
What Flexi should call you. Your email address is not a name, so the field starts empty until you give one.
The first way to get a picture is the cartoon you: from a photo (a clear face, nobody else in it) or from a few words about how you look, in one of seven looks or Surprise me, with anything to add (a guitar, your dog, a hard hat). It takes about twenty seconds, the colours are a surprise, and you can draw another. Below it: a photo as it is, your Google photo, or your initials on one of eight colours. Whatever is picked is saved with the button.

On a return visit the page has two more tabs, Flexpert page and Requests: your public page as a flexpert and what founders asked from it. The flexperts article has both.
