The plugin is good. It works. but the only problem I have is i want to change the email address used for the mail list to a different email address (more official email address). Also the plugin does not show you the list of email addresses that has been in-putted and the time and date of registration.
So in essence it is
Using a different email address that is separate from the admin
The plugin does not show a list of email addresses in the database that it has collected.
