This will extend the 1.9 tagging features (tagging users and blogs) to allow users to tag courses. See http://openlearn.open.ac.uk for a demo of roughly how it will work (post Jan - not live just as I write!)

Essentially the tag block will also cover course tags, and the tag display will have an extra section listing course tags with a display similar to the course search screen.

This will also add the ability to toggle the view of tags to "my tags", "official tags", "community tags" and "all tags" in the block for better personalisation.
