Talk:Private wikis

Semi-private
Hello there! I have a question. What if someone wants to have a semi-private (or semi-public) wiki, with some page public, and some private? Is there a way to do that, and is the privacy is real (no chance of bugs exposing the private pages to Google or to wiki readers?) What are the different level of privacy? I guess one of them is to forbid search engine crawler bot, so only the wiki readers can access the pages, one other is to allow users by name, with rights, reading or editing, but what are the other possibilities? Can a template make private pages (only allowed users) and public or semi-public pages?
