You will be prompted to add a short bio about yourself when you first login to ProgressPod.io.
Only you, the other people in your progress pod, and the Membership Owner and Admins can see your Bio.
Your Bio can be a maximum of 500 characters long including spaces.
If you cannot save your bio it is probably too long.
Try entering a shorter bio.
You can edit your Bio in My Settings > Profile
My Settings can be found in the Main Menu at the top right hand corner of the screen.
