Thread:Project:Support desk/Protecting pages and parts of/reply (2)

Seeing and editing pages are two different things; even MediaWiki can differentiate between those. It is possible to protect pages in a way so that only users of special groups can edit these pages. However, to me your idea sounds like you would need hundreds of groups (for different families or relations). MediaWiki does not offer a way to have groups set up automatically, possibly depending on some user input. You would have to create all these groups yourself. And I don't know, if combinations of groups would be possible for one and the same page.

I am not sure, if what you want can be done easily with MediaWiki. MediaWiki is not made for access control. If you want that, you should not use MediaWiki, but a CMS.
