I don't mind other opinions, but when I click into a multi-page thread, it takes me to page 1. Then I have to click "jump to end" or "first unread post" I'm not talking about replying to an existing post. And most message boards I've been to have the reply box at the bottom of every page, not just the last page. Your reply is added to the end of the discussion, because that's what the message board software does. The software here does the same thing, as far as I can tell.
Today, I knew that there were no unread posts -- I had been in the thread five minutes earlier. So I scrolled to the bottom of the first page expecting to see a reply box, and there wasn't one. The only way I could get to a reply box was to go to the last page of the thread.
That's what prompted my post.
