Hi 7T7,
Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
At the top of the page you will see the line with all the tabs, click on "Tools" and you will find all kinds of manuals. Some even written by members that actually use the item.
In the line where your name appears at top of page click on settings, on left side find and click on "General Settings" and then scroll down to find "Thread display mode". Change the order of post appearance there.
Be sure and check out our
Heartland Owners Club. Join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.
Enjoy the forum.
Jim M
