Is there a way to make certain pages or even the entire wiki inaccessible to anyone who doesn't have a rank? It's not just that I want them to be unable to edit it, but that the page would be impossible to find altogether. There is a way to "comment" in the code so that some text is only seen when you edit the page, but I was thinking of a bit more than that as you can see the code even if you don't have permission to edit.
This would be for a wiki that is still new and under construction so would make pages but not release them until they are finished and all the info on it is confirmed.
