I'll test. The best idea would be to give each person an unique username and password and if you have any competence on php make it so only two different ips are allowed per program but cannot be logged on at the same time.
I'm using Registry and CDO to make it store a Unique Machine-dependant Serial... The problem is I'm having problems * <--- LoL :lol: I don't have experiences with php, so I can't use such methods... Meh, I'll look for something to make it work...
Another idea is to encrypt teh username and passwords on a website when the user clicks to authorize it goes to the site and see if the username and pass enetered are on there
