..... How would you reply to a single individual?
You can use the "quote" function as per Carol's diections, or you can just reply on the thread, and direct your reply to the person, mentioning their name.
You can also send someone a personal message (PM) which no one else can see. This is generally only used for private conversations, often regarding living people who we are not allowed to mention on the publuc forum. It is not really advisable to use PMs for topics that are being discussed on the boards as well, because it is impossible to keep track of replies given by others and it can all get a bit messy.
