How do I add a friend?
To add a friend, just go to that member's profile page and click the "Add As Friend" button. A friend request will be sent to that user, and if they accept, your profiles will be linked as friends.
To find a member's profile page, just go to http://www.myfitnesspal.com/[USERNAME] but replace [USERNAME] with their actual username.
If you don't know your friend's MyFitnessPal username, you can search for them by clicking on the "Community" tab, and then clicking "Find Members."
