I have started looking into the adding of existing modules using the core DNN functioality and have run into some issues that I was hoping someone could confirm.

Problem 1:
I have a page that contains a bunch of descriptions that are used through out the site. When i need to reference one I set the setting at the top of the admin page to "Add Existing Module" and add a reference to a module on my definitions page. This works fine the first time, but then if I do it again and nothing is referenced. This provlem only happens when the caching is set to moderate...if I turn caching off everything works as it is supposed to.

Problem 2:
How can I tell which modules reference other modules?

Problem 3:
Is there a way to copy and not reference another module?

thanks.
