it would be for a library reservation system. this would be put on the computers with sessions from 15 minutes to 2 hours (in 15 minute chunks i.e, 15, 30, 45, 1 hour).
this program would countdown the remaining time on their session, with pop-up messages appearing every so often.
at the end of the session, the program will have to automatically log the user off.
can anyone give me a helping hand to get me started.
