It was requested some time ago by a fairly prominent member of the community, that diarists be given the ability to make comments on their diary private if, for example, someone has left a comment that was for a Friends Only entry but the person leaving it had left it as a public comment.
I am pleased to announce that said feature is now in place. If you wish to make a comment private that was previously left public, you can now do so by clicking on the 'privatise comment' link which is alongside the ban user or delete comment options. Once made private there is not an option to make it public again, since I can't see why you'd want to and I can't be bothered to produce something that's of little use.
If there's any questions, problems or suggestions please feel free to drop us a line.
Steve.
