Hello all, I'm quite new to the nofollow/dofollow aspect of things, trying to make a determination. My blog is currently a DoFollow ( http://www.knesekguns.com/blog ) - if i get a great deal of comments, is it going to affect my main url ( http://www.knesekguns.com ) from bleeding PR? I currently have a PR of 4 on the main site and don't want to lose any Thanks for the help in advance!
PageRank is the calculation used to determine the value of links pointing to your site. So whether or not your blog is spammed it should not have any effect on your main site PR 4
