So you have a content type that you created with CCK that has more than a few fields. In some cases, you don't want all of the fields to show up when viewing the full node - luckily, there's an easy way to hide individual fields without resorting to theming tricks or PHP code.

Simply go to the content type's "edit" page (assuming you're logged in as an appropriate administrative user) and click on the "Display fields" tab. From here you can hide or exclude individual fields from view in both teasers and full nodes.
