Thanks for the alert. The link does show an update that claims this was a mistake. Not that it isn't going to happen, just that it was not meant to be seen by so many folks so soon. I've never used all the free space I've had and now have a TB at MS, should I ever decide to trust
them! DB has always wished to be a commercial product, the free storage has always been minimal in size and scope, but it did fill a need. Once a company becomes public, it often becomes more concerned about its stock price. It used to be unique, but cloud storage is now a commodity and it is fairly easy and much cheaper to set up now that when they started. But all that means there is also more competition.
It was useful while it lasted, I've got lots of local drive space. probably time to 'drop the "box"'.
