Hi there; I'm running the latest version of both this plugin and WordPress. We have some people who were auto-subscribed when they signed up for a website account ("Registered Users") who don't want to receive our post notifications anymore.
When we attempt to unsubscribe them by searching for their email address, and then using the Bulk Management area to select all the categories, click the Unsubscribe radio button and then click Bulk Update Categories, we get the message that the user has been unsubscribed, but the person continues to receive the emails.
Is there a way to delete their email address entirely from the Subscribe2 system? They want to be removed from receiving mail about all categories anyway, and some of them are quite irate that we keep mailing them.
