We have developed a wiki-based platform , called the WikiDesignPlatform (WDP), which couples (as required) additional components (e.g. email, instant messenger, CVS repository) with the traditional wiki and automatically produces detailed transcripts of all the online activity by the users, far richer that the average "recent changes" history provided by most wikis.
