Tour of a group page.
The main panel on the group page, under the description, is a list of the most recent discussion threads within the group.
You can search for threads within the group by clicking the search icon.
If a discussion is no longer revelant and you’d rather it wasn’t in the list, you can close it. Open the thread, click the dropdown menu, and select Close thread. Closed threads can be found if you click “Closed threads” on the discussion list.
