And Jean - there is another trick that is similar to the old American television panel game show To Tell The Truth where three of the four panelist tried to impersonate the identity of the real character that you could use to make it appear that there is a glossary on each topic.
Of course you need to create a single glossary and make sure that Activity names auto-linking filter is turned on for the course. Then you create label that has the same text as the Glossary activity. You can even add the icon image to make the label imposter appear more like and the real Glossary activity.
In the example below there is only ONE Glossary activity and two glossary label imposters. Can you identify which one is real. There are some subtle differences but it fools most of the users. You just need to make sure that the user know how to get back to the course.
I generally put activities that I want users to use multiple times in a general resources topic and the labels in the other topics.
