With this script it is very easy to add new users.
I use my own shell-scripts to add users but I figured out, that some people does not like the terminal or konsole as much as I do:-)
So here is a script using kdialog, which is required.
For me it is also a study to show some of the great possibilities of kdialog.
Just put it within your PATH and make it executable.
How ever, have fun with it!
