SealedWiki is a derivative of WardCunningham's QwikiWiki that permits users to write-protect portions of text inside an open wiki environment. The site adds extra security to the free-wheeling wiki concept without requiring userids. Anyone who want to protect a portion of their text can do so by enclosing it in a unique password-protected seal. Please take a moment to check out http://www.sealedwiki.net/cgi-bin/wiki.cgi. The sealed wiki approach is ideally suited to forming discussion threads using nested seals.
