I love your plugin but, I have a question. I have over 58,000 confirmed registered users on my site. I clicked the button to import the registered users but, only a little over 12,000 were imported. I clicked it two more times and just around 1000 more were added each time. Do I need to contiue to click the import button until all the users are added? Is this the normal function or should all of the users have been added the first time? Please let me know. Thanks!
