News Management Explanation

Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/bedc04e835bd6cdc#

I would like some information on the following In-News fields:

• Start Date
  • is the news hidden before this date and appears automatically?
• Archivation Date
  • how does it works?
  • how could we use it in suggest form (name of the field to be used)?
• Archived element
  • how to display them, any existing tag?
