The site you are viewing is a WikklyText wiki. If you are familiar with TiddlyWiki you'll notice that WikklyText wikis use the same naming scheme. This is done so that you can move content freely between a TiddlyWiki and a WikklyText wiki. (See the wik conv command in UsingWik.)

Much of the time, this site will be running a prerelease version of WikklyText. Don't be surprised to see a version number (on the link at the bottom) that is not yet available for download. All features will be included in the next stable release.
