Only current users of MyFitnessPal can be invited to join a Group on the site. To invite an existing MyFitnessPal user to join a Group, go to the group you created under the 'community' tab, then click the 'Groups' sub-tab. Select the group you'd like to invite your friend(s) to, then on the right side of the screen, click the '• • •' menu, and click 'Invite Members.' Once the new window opens, you can enter the MyFitnessPal username(s). You can also do this from within the group, but click 'Options' instead, and you'll see 'Invite Members.'
