Aha, I understand, I didn't really want to split it down into too many categories, let's wait and see what the guy who developed the glossary says, I've asked him if he can change it so that duplicates are allowed. Thanks for the input though.
i think this will be not so easy to change, because the function, that saves
the entry uses the savefunctions from the mambo db class. You have to change
the whole function to use own db-commands to save the entry to the database.
I can change this first, when I work on Glossary 2.0 but at this moment, i'm
very busy with my homepage.
