How do I start a discussion?

You've already figured it out. You can post a Question, an Update, or a Shared Link. This post uses the Question feature. You can also post an Update or Share a Link by clicking on the appropriate header, as shown in LTC Jason Mackay's response.

SFC Bill Snyder just like this. Your choices are from HOME at the top left, MY FEED. Select a question, update or share a link.

CLICK ON "HOME" THEN CLICK ON ANSWERS ON THE DROP DOWN MENU.
