A few days ago I noticed that every board and every tipic of the smf FORUM http://www.simplemachines.org/community/index.php has PR 7. If you are a member of this forum you can have a signature with no restrictions at all. You know what to do now PS: Some good Reputations for me are very welcome
I don't know what page rake software you are using to check with, but I'm not picking it up with any of the topic or boards. I use http://pr.blogflux.com/index2.php
Icedout is correct. Your PF checker is not accurate. The site doesn't use unique urls - it has one page "index.php" with query strings that trigger the different data on each "page". Most non-Google PR checking mechanisms will read it as having the same PR as the main page of the forum. If you really want to see accurate PR, check with Google Toolbar. You really don't want to get hung up on PageRank though...A couple weeks ago, Google dropped a lot of sites' PR and their rankings didn't change at all.
I dont think so SMF having PR7 in all the topics at all. I have been using SMF since long. Only home is having high PR.
