SpinnerWiki is a WikiClone hosted at SourceForge. It was originally based on DolphinWikiWeb. Unlike DolphinWikiWeb, SpinnerWiki supports only one web per CGI script (but of course you can make multiple copies of the CGI scripts).
SpinnerWiki has several new features beyond what DolphinWikiWeb has, many of which are designed to remove the need for HTML markup in DolphinWikiWeb pages. There is Wiki markup for headers, literal code blocks, and tables among other things. There is also a loosely integrated file-upload facility. SpinnerWiki is nonetheless a relatively lean, simple WikiEngine compared to some of the modern fare like TwikiClone and OpenWiki. Setup is very simple.
http://spinner-wiki.sourceforge.net/ <- This web site seems to be vandalized (as of Oct. 1. 2004). Is there an alternative access to the source? (please feel free to remove this comment, if the problem is fixed, A. Schleth)
I tried to fix it as much as I can (20 Dec 2004). We'll see how long it lasts. I'm currently using SpinnerWiki for an internal wesite. The source for SpinnerWiki is at http://sourceforge.net/project/showfiles.php?group_id=52873 ChrisRule
