When someone logs in, save their ID somewhere. If they try to log in again, check where you save the names and see if it's there.
Checking my crystal ball, though, you're going to run into problems. What if I log in, accidentally close my window, and then go back to try and log in again. Odds are your "security" feature will not allow me to log in, because it thinks I already am. Bottom line, why worry about it? ---John W. Holmes...
