It would be nice if in any wiki page, the history could be navigated by a lecturer/instructor in such a matter that changes by user could be easily identified and tracked. It would help to use wiki as a tool to evaluate a students contributions to a wiki page (student work, etc.). I mean something such it can be performed nowadays with Open Office suite programs through the "file>versions>compare>filter by author" option, and navigate through this person's changes. Xavi
