Say there's a high pr (pr7-8), do-follow forum thread that I want to add a reply to with a link to my page. The thread is 10 pages long and only page 1 is showing pr in the google page rank add on. The other 9 pages are showing pr 0. For the link juice of the first page to reach my link (my link would be on page 10) would I have to get google to index those other 9 pages? Also, by the time the link juice reaches my page after going through the other pages, will the link juice have diminished so much that it's not even worth indexing them? Oh, and pages 1-8 are over a year old. So I'm guessing the reason the pages aren't showing pr wouldn't be because Google didn't update.
