At the moment, if a seller lists a new listing and it goes to the admin for moderation, it’s a bit cumbersome to track down that seller’s email address to communicate if there are issues with the listing that need to be fixed before it can be activated.
It would be nice to have a message system where admins can message new hosts/vendors before they are approved.
