Many wikis have a WikiNode or similarly-named page, grouping related wikis for ease of navigation between them. (This is the same basic idea as WebRing, except here it is shown not as a small feature on each page, but as the main content on a specific page. For part of its origins, see http://wikinodes.wiki.taoriver.net/moin.cgi/WikiNodesProject)
Historical Note: use of the "CamelCase" format, as in the name of this page, arose in the days when page names had to be single "words". We don't need to use it here but it's harmless and friendly when relating to sites that are stuck with it.
