Re: Surely...
I was fighting with just such documentation a couple of days ago. The crucial missing information (amongst lots) was "this option will not be displayed unless you have the appropriate edit permissions, and there will be nothing displayed to tell you that you do not have the appropriate edit permissions".
I mean! Are people *REALLY* still doing the "remove the option until certain condition fulfilled" thing instead of "grey the option until valid SO THAT YOU KNOW THE BLOODY OPTION ACTUALLY EXISTS".
