Great! @Bonapara should there be an acceptance screen upon signup to make sure we don't throw them into a new workspace if they don't want to? Or as a v1 we just add them to every workspace with a matching email domain and log them to the first one? Or only allow one workspace per email domain? (but what if someone steals it)

Also, @AMoreaux we should make sure that only work emails can be added in there so that people don't trap gmail/hotmail users into workspaces.

Let's do that!
