Having a wiki might be a good way of making it easy for people to contribute documentation. I think we'd need one that supported logins for editing, and had good revision control.

We've used wiki's internally, and they've worked quite well for some projects. There's always the danger that it would be yet another source of incomplete and potentially out of date information. However, perhaps we'd end up declaring the wiki to be the definitive version, and adjusting the READMEs etc just to point at the wiki, or perhaps auto generating them as a snapshot of the wiki. It would certainly be good to pull together Jan's FAQ, and all the various HOWTOs. As with any kind of documentation, the trick is in having a good editorial team...

Have you used MoinMoin wiki? We've found this to be the best of the bunch we've looked at.

It's a pity sourceforge don't provide a wiki facility. It's also a shame that their mailing list archive isn't as good as the gmane.org one...
