Hi Merry @merpreb, if I remember correctly the discussions were sequential by post until someone replied to a post in the middle of the discussion. Then that post was a newer date but a reply to an older post. Multiple that by a lot of different replies to different posts in a discussion and it made it sometimes difficult to follow a discussion. The change was that now you sort the discussion by selecting Newest to Oldest or Oldest to Newest at the top of the discussion which will give you an ascending or descending "flat" view of the discussion so that you see them in order. When someone is replying to a post there is the "show post" link to show you the post that the person was replying to. @colleenyoung can probably describe it better but flat is an old school term that I probably remember from a previous life working with programmers ☺
