I have searched the threads on thsi forum and found a way to retrieve a user on your site's MAC addr via an ActiveX control.
However, an ActiveX control does no good to someone using a Mozilla browser.
Now I have seen sites that will tell you things like your IP, DNS name, and MAC without having to accept an ActiveX, and will perform the same in Firefox.
Now the reason I am asking this, is I am developing a text based RPG game, and as we all know, people/kids can be a problem.
Sure I could ban them by IP or Email, but in todays world, and IP change is simple, and emails are free.
So, Does anyone know how to do this?
