when asked for your username for the first time(as in right after the info screen that tells you about root and toor password)

if you give a uppercase username then everything that follows is automatically upper case

I dont know if the passwords are case sensative but i think so...

and that might be a problem if one has a uppercase username and lowercase password also i've got a password problem so haven't been able to test this just thought id post it here people might wanna check it out...
