I am thinking of using DNN to give my IT department a much needed documentation system, and a Wiki seems like a great way to go with getting several processes and systems documented. What I would like to do is create a hierachy of topics in a tree structure to allow different subject areas to be grouped together. Does this Wiki module support this?

In addition to this - or even alternatively - I would like to keyword or property tag the various pages to allow logical linking between them automatically without having to go locate every related page and update links in it. For example - All our Denton servers might have pages detailing their hardware and hardware service history, I might also have a page dedicated to FooBar app that runs on one server and stores data on a SQL server on another machine, and serves out through a VPN router. I want to be able to follow a branching breadcrumb trail through all these different topic areas - Server Hardware, FooBar app, Data Warehouse, Network, and Security Compliance Documentation.

This may sound ambitious, but if I could have a keyword property on a page, and then click on that and see an index of all pages sharing that keyword, I could do what I envision.
