While waiting for help with my other issues, I'm charging ahead implementing the entire API. So I THINK I have found two missing items:
1. /surname
needs an ID value. But where the hell can I FIND this value? Perhaps a
/surname /search ?name=[last name] is needed?
2. /user
a glaring omission is that this API does NOT return an ID or GUID? If I had that I could use the /profile API, and look up the info. available for any other Profile.
