I know how to do this on redhat, most distros all have the same commands. Logged in as root type adduser o useradd (they both do the same)

This is how you use the command:

The example which follows shows how to add a new user account. It is for a user named "John Pong" with the username "jpong" and home directory of "/home/jpong/".

# adduser -c "John Pong" jpong -d /home/jpong

Type this in and it will make an account for the user. Now goto your homes directory by typing 'cd /home' and issue the command 'mkdir jpong' to make his accoutn folder.

Now that you have his account made, all you need to do is set his password by typing 'passwd jpong' and just follow the on screen instructions. Hope this works, so you can go home and have a merry christmas!
