We used to have a Zope-based wiki here, but when our hosting imploded in the spring of 2004, we unfortunately lost all of the content. We re-instated the website as a MediaWiki, which unfortunately doesn't do ReST, but has other nice features. Thanks to j^ for installing it for us.
Anyway, please help repopulate.
A site that could help with repopulating is the Web Archive. Access this URL to get archived versions of the old Wiki: 'http://web.archive.org/*/http://wiki.xiph.org' Please note that in some cases, links such as 'http://web.archive.org/*/http://wiki.xiph.org/FrontPage' or 'http://web.archive.org/*/http://wiki.xiph.org/FrontPage/editform' might work better. (Adjust as neccessary.)
