I want to make my Wiki so only members (Not Anonymous users) can edit. I'm afraid that when I tell my friends about it and others, trollers and those type of people will come and mess up pages. And as I said before, I don't want trolls so I don't really want to say the wiki. But is it possible for members-only to edit or even having specific people able to edit pages? And It's okay if there isn't because I know the undo button on the 'History' for pages.
