This is a personal MediaWiki...
Getting started
The User's Guide will explain how to use the WiKi software, to Dirk (the owner of this Web-site).

Some Experimentation with MediaWiKi
The first page on this site started as an addendum to the Getting Started page that the MediaWiKi software shipped with. Now that that page is fleshed out, it has also been converted into a standalone page.
