If you have signed up for a profile and it is not appearing in the People list your profile did not get saved during the sign-up process.   Log in to your account and  and click the Profile Tab.  Next, open the set-up wizard and check if there is a Red X by any of the requirements. If there's one by the profile setup then you need to click "Launch" and click the "Save"  button. Then your profile will be viewable on the network.
