From the main forum page, for the really long threads, you can go to following pages directly: 1, 2, 3, 4, 5, 6, and Last. For a couple threads, last is "9".
Last night, I knew I was on page #8, so it was irritating to have to go to page #9 first, then back to page 8, then back to page 9.
This only matters, of course, when a conversation is interesting enough to reach 7 pages or more. So don't re-program anything but if it could be fixed I'd appreciate it.
Or perhaps there is an easier way to get to oldest, unread post?
