??? What is your postnuke version?
If there is no description, there is no link to event full information even if you have location, contact and so on... i think there should be always a link ...
Yes, you will have to prepare new template(s) if you add fields to your publication. The standard templates operate with dates, title and text (content) only. Hence, having a link to empty content would be waste of user time if the user clicks to see more. If you don't like this feature or if you add more fields you will have to make appropriate modifications to the templates.
