@rolyhu If you click the Reply button beneath a members post, you will see their member name show up first in the comment box where you type. The member name sends a notification to the member that someone has responded to their comment. You can also type in the Post Comment box at the bottom o a page and anyone following the discussion will be notified of your comment. Using the members name in your post insures that the member will receive a notification.
