This plug-in allows you to batch import of users/members taken from an uploaded CSV file.
It will add users/members with basic information, including firstname, lastname, username, password and email address.
Each user who is added will be a ‘subscriber’ if value not provided in csv file, and be able to login to your site.
You can also choose to send a notification to the new users and to display password nag on user login.
There are no additional options available at the moment, but if you want to add a bunch of users in one go, this will do this for you quickly.
