Answer 1

There is a professional good way for that:

1) First of all, Use a core user system for all Q2A websites (external users).

2) Then in qa-external/qa-external-users.php use $_SESSION variable in qa_get_logged_in_user function.

3) Finally use `session.cookie_domain = ".{your main core user system domain}"` in each Q2A php.ini website (each subdomain).

I hope that helps you
