Video Suggestion: Bookstack

BookStack is a simple, self-hosted, easy-to-use platform for organising and storing information.

Having seen this become more popular on some of the technical forums I frequent and remembering you use MediaWiki I thought it would be good to flag this up to you. Great system especially for small businesses, easy to setup and looks great with a clean interface and permission set.

While it looks nice, it does not offer the file features and file versioning that MediaWiki has.
