How to schedule a cron event that will import users from a specified file on the server?
I had a user ask me by email how to do that, so I released version 0.5 to make the plugin more extensible and I am posting the solution here for anyone who would like to do that in the future.
The plugin now has a function called IS_IU_Import_Users::import_csv( string $filename, bool, bool ).
The first argument is the path to the file on the server.
The second one is whether you want the password nag to be shown on first user login.
The third one is whether you want to send email notifications to the new users.
