No warning? If the user can read, here's the default welcome message:
It says please don't, it does not say can not.
AS a user, I would expect hitting the reply button on message from person X, that the reply would end up with person X.
The welcome message is just an example. A user that sends a PM, deletes it to keep his box clear (there's a PM limit, so they keep things as tidy as possible, with the current system you would have to save every PM you might expect an answer to).
As far as sending one and not adding any other users. It's intended and will have a future use.
Well, all in all, with the current system, it's confusing for users. Atleast there should be a warning, and then maybe an option to start a new private topic.
