This issue seems to have gone quiet in the last year. We're using Moodle 2.x (not quite sure which) and I've had students create a glossary and some of them have pictures.
If they move to a new group as they change year group in September, I'd like them to take their definitions with them.
For some reason I don't seem to have the time to add all of their pictures in again - my wife's a Moodle widow as it is!
