One small item : if a thread causes a lot interest and goes beyond the 99-reply display, we start another thread -- it is merely polite to post the switch at end of the 99th post.
For example the first thread might be "Love" and the 99th or 100th post would start as "Love 2" or "Love II" depending on your erudition and inclination to display it.(grin)
It doesn't happen often so the 99 display in Preferences is usually sufficient. Does that make sense?
Welcome ! and very happy posting.
