Well, Ludwig got a Wiki, so it was inevitable I needed one too. As usual, there seems to be no simple guide on the web to get started building one, so here it is:
- Wiki - Wikipedia, the free encyclopedia. Here's a good general overview of what the heck a Wiki is and a history. Kind of cool that this description is itself in wikipedia which is of course a Wiki.
- Choose a software. As usual, there are a bunch of them. The big four mentioned are MediaWiki, MoinMoin, UseModWiki and TWiki). The Wikipedia uses MediaWiki, so that's a pretty good endorsement.
flexwiki was very easy to set up but it is asp based so your hoster may or may not support.
