When a discussion thread rotates off the Main Page or a Group Page, it goes into the archive.  There is a wealth of information and opinion contained in those discussions (6,980 Forum Discussions) and with room for only 10 Main Page discussions a lot of valuable content can be missed.  In cases where there are multiple discussions on the same topic or duplicate posts of the same discussion, members may be asked to delete the duplicate or move their question/comment to a single discussion.  The reason for this is to facilitate searching the archive.

To search the archive, go to the command "View All" at the bottom of the Main Page or a Group Page list of current discussions.  Click on "View All" and you pull up a list of all the archived discussions.  To search through all of those discussions you need to use a key word or words.  Examples:  Pipeline or Right of Way,  Decline Curve, a company name, etc.  Enter the key word(s) in the search box and click on the "magnifying glass" icon to the right.  The default order of the archived discussions is most recent to oldest.  Many subjects have evolved over the history of the site and old comments may no longer be accurate.  If you don't find what you are looking for you may need to try multiple key words.   Give it a try and ask questions if you need help.  Good Luck, Skip
