This is probably understood by most of you who have been reading this discussion site for very long, but just in case you don't know, to see all older posts that have been recently replied to, you can just select "LAST MODIFIED" in the small drop-down rectangular box.  It's on the lower right of the page (underneath the list of subject lines). By choosing that option it will re-order ALL TOPICS beginning with the very latest ones that have received any additional comments/answers (even in the last few minutes or hours), and that includes all posts, even posts that were started many years ago!   

I find this a lot better because if you come on this site and are not signed in as a member, the default order shows the posts by the "START DATE", meaning that in a few days time the older posts get farther and farther away and you will never see any later replies to those earlier posts unless you scroll back through many pages of old posts . 

Please excuse this if you already know it.........just trying to help any newbies that might not be aware of this.
