If you're ever faced with creating user accounts for a large existing group this is your tool.
So, simple to install and use I had my 50 user accounts created in less than 15 minutes.
Using an existing member list in Word I created my CSV string. Copied it to the component's field and had my accounts in no time.
Just be careful to follow the string's format requirement. If you miss a comma, or don't place your fields in the proper format (name, login name, email, password) you'll have a problem.
