Alright, well . Here at expl0its, it's designed to fit Unet.
Most Websites on Unet, are free email registering . So, some people just randomly type in an email when registering to a website.
Sometimes, people don't know that their email is already in use , So ~
It sais ' this email is already in use by another Unet user '
All you have to do, is make a fairly random msn ,
And use that. Remember the msn , As you will need this to log in.
Thanks, Expl0its Staff
