Continuing the discussion from The Society's Community "How To" Guides:
When you visit the post summary (at the bottom of the first post in a thread), you will see a list of participants in the conversation. If a member has commented more than once, you will see a number above their avatar. Click on the avatar to bring up the member’s information, then click on the “x posts in topic” filter that appears to see only a list of their comments.
A fascinating option in the community is to apply an automatic summary of a long thread to show you the most interesting answers and comments.
This option only exists for conversation threads that have over 50 comments. It may be hard to find the proverbial needle in this haystack, so the option to “summarise this topic” (see image below) highlights those comments with the most likes and replies in order to give you a quick sense and overview of the full conversation.
