Maybe they can both be used as learning management platforms? That is Moodle’s role, of course, but some one somewhere is no doubt using a wiki as such as well.
But no, that’s not what I meant.
Both the Confluence wiki and Moodle have Microsoft plug-ins that allow a user to open, edit and save directly back to the wiki or Moodle room, any Microsoft doc or spreadsheet! (Obviously you must have Microsoft’s Office Suite installed on your local desktop).
Thanks to Roger Goodson’s blog for putting me on to this.
