TOPIC: Possible to show cal OR event list on registration page?

I'd like to show additional events on an event registration page using a module. Unfortunately there is no way to add a menu link that includes all registration pages so I can't set up a module to be shown that way

What do you mean you can't create a menu item showing all events? Create a List of Events menu item. That includes events of all categories. The calendar view as well. Then in a module, you can use our mini-calendar module or the upcoming events module for a listing.
