How to see again "Terms and conditions"


users can accept terms and conditions once, but aferwards they can’t review it (with its acceptation date).
May be could it be possible at the bottom near “Help” and “About” or in the Preferences?
What about the version number of these TaC? Is it used somewhere or is it just for the author’s information?
At first thought, i believed that incrementing it would force the users to validate the new version.
But it is not a request…
