I think you misunderstand. I'm asking for the ability to email all users with a current ad in Classifieds via the admin panel. Or to be able to export the email address of members with a current ad.
I have 92,000 members. Only 420 of them have ads in Classifieds at this moment. I don't want to email 92,000 people to warn the 420 people with current classified ads that a scammer is operating in the Classifieds today. Or for any other problem that just effects the Classifieds.
It would be an important addition to the Classifieds.
