[Sigia-l] Collaborative "help system"

[Peter Indelicato]

Hello everyone -
   
  I am looking for input and experience on a help system authoring tool / wiki / CMS / whatever that could be used collaboratively to author self-help content that is published via DHTML.
   
  Can anyone recommend a tool that...
  ...allows anyone (with the right permissions) to edit content through a web browser
  ...allows the use of "rich" content, like embedded flash
  ...provides some sort of approval or rollback capability
  ...supports contextual help
   
  General advice works also.
   
  Many thanks - 
   
  Peter
