Login Manager and Adding another user for Knoppix

[Drool King]

I just installed Knoppix 3.6 on my HD (with kernel 2.6). I got it running on my hd but I dont get a log in screen (not like my RH9 - where it asks for who will log in). It is always user KNOPPIX. (no password). I also find it rather unusual that built-in (???) users are about 20 which doesn't have any passwords nor log-in screen. Could anybody please help me how to get to a log-in screen and add another user. I want to give my kids their own log-in screen and their own desktop (same as RH9 and WinXP). I am also reading some FAQs on their forums but no definite answer found. Any help would be very much appreciated. Thanks.

as root do:

useradd -m -G users,audio,games -s /bin/bash username

then

passwd username
