Thank you for your response. One more question, please:
If I install the plugin on this site with 90K users with Email Verification ON, what happen with all existing users (who obviously didn’t verify the email before I installed the plugin). Will be these users considered as invalid?
Or, the mechanism to validate users only affect the new users *after* the plugin is installed and activated?
I want to start using your plugin but I am wondering how it will treat existing users.
