you could write a script?
First create a doc with all new users you'd like to create - each on a new line.
Let's call file newUsers
next create a script with this info in it:
Code:
#!/bin/bash
for i in `cat newUsers`
do
useradd $i
done
You could add more to script as well - like if you'd like to set passwords just add passwd $i on line below useradd $i.
As of right now I personally do not know of a utility --
