I love being able to import large numbers of potential users, but what good does that do me if I have to market to them (and track that marketing) in another program? I want to be able to send them a welcome email to say, "hey, you have an account waiting to be activated over here, all you have to do is follow this link pick a class to take, and type in this login info to pay for it." This shouldn't be a difficult update, right? Just toggle to allow messaging for inactive users?
