[Serusers] ser.cfg tuning question

[Bogdan-Andrei IANCU]

from performance point of view, is better to use a flag instead of 
calling several time is_user_in - which is slow because of db 
interaction (even if there is some caching, you still go through the db 
engine - mysql library).
the flag operations are very simple and fast implemented.
