which better inherits PR, sub? or directory?

[mastipolo]

HiFirst time here, I dont know how I missed it before! ...excellent forum!I have a forum with url as a subdomain: forums.domain.comAlthough my domain index page had PR5, the forum, which has its link in the index page, gets only 2, although the index page has no other links but the forum's.My question is: is it better if the forum had its url as: domain.com/forumsdoes that makes it have a better PR in google, inherited from the domain index page?or is it the same, be it forums.domain or domain/forums?well it shouldn't but I had a pr5 site and linked to it to /forums and it got pr4 nearly 5how do you know it was nearly a 5? lol
