Hey timbo343!
I know what you mean - exploring any software is always good fun in what you'll find
I guess at the moment you could say that this is working as it was first intended, which was it being added together with Windows 8 live tile updates. The reasons for not putting the environmental dashboard behind a user login is because the live tile information can't be login protected, and so in turn, neither was the dashboard. We've designed this to contain as little information about the user as possible, but can definitely see students getting a bit of a big head if they found out printing habits!
We've always recommended that if this were something that caused a few issues, then you would be able to turn if off via the Options -> Config Editor, then searching "user.environmental-impact.enable" and changing this to N. This will mean that the environmental details for each user is completely disabled though. When it IS disabled, the URL is still able to be viewed, however it will show the entire organisations usage rather than being able to see a specific users print habits.
We also have got a lot of requests about developing a way to password, so I'll add this as an informal request for development!
Sounds like it wasn't set up to disallow transfers when people were unrestricted! Always a fun one to play with that feature when you have infinite money!
