You'll quickly learn how you need to see ALL the properties of an object, be it a channel, posting, or resource. It wasn't until today (go-live) that I took the time to write a little WinForm app that shows you EVERYTHING about an object. All you have to do is provide it a MCMS path or object guid and it shows you EVERYTHING.
