Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
I'm starting to figure this out, too. Just found out that individual replies to a topic can be bookmarked, also. For me, it allowed me to bookmark a recipe that was posted in a thread and now I don't have to scroll through the whole thread to find what I'm looking for. Some of the old threads may have 40+ pages of replies.
