Hi,
How can I do this:
1º-Registration form with button “connect with Facebook”
2º-Get the ID of user and save in my own server for count the registration in real time.
3º-Know in what level be the user by my server (when the user have internet connection I can see in what level he/she be).
4º-Know the device that user use.
If you not know some question but know others, please reply to me too.
Thanks in advance!
