The software that runs wikipedia, MediaWiki
, is free and easy to setup. For administrators, I've found the toughest part of wiki setup and administration is the level of customizability. The initial setup is simple, but thousands of combinations exist to make the software work exactly how one wants it to.
For users, learning proper wiki markup can be a bit tricky. Text articles are simple. Just type. However, we'd want a real wiki, with links that explain other topics, so users can read more in depth on subjects they may not understand.
Disregard the maturity level of NS users. Everything that gets published and posted goes through an over site committee.
