i don't like such (stupid)tools, mostly bad written shell-scripts...
try to learn unix
for a new user you need 5 steps
1, edit /etc/passwd and append the new user
you can duplicate an existent user, delete the passwd field, change its uid, gid, gecos, home-dir...
2, edit /etc/groups, appropriately add the new user
3, mkdir the home-dir of this new user
maybe in /export/home or /home or ....
4, chmod -R newuserid:newusrgid user-home-dir
5, set the passwd of newuser using the /bin/passwd cmd
manual pages helps you
