Dan Holohan, creator of HeatingHelp.com, explains this newest feature now on the “Wall,” his HVACR and plumbing message board.

“I opened a new room on the Wall for Round Table discussions. It works like the Wall but it will stay focused indefinitely on a particular topic. To access it, go to the main page of the Wall and click on Options. Then check Round Tables in the Forum section and they'll appear at the bottom of the Wall the next time you go there.”
