Is it possible to subscribe individuals to an entire list rather than only a card? I want people to be able to get email updates on all changes to all cards in certain lists without having to drag their names to each individual card. Is this possible? They can view it all, but it is the email updates I am concerned about.

I hope we're going to see it in a week or two.
