Say I go to a forum with a PR6. I go to one of the sections and post with my signature in an individual thread. The thread has no PR or has a PR0, what kind of back link credit to I get? Is it worth it to do this? I also notice at DP that people sell posts with links on their PR weighted blogs. After the post disappears from the first page and goes to archive, do you still get any real PR credit for that back link? Again, is it worth it? Thanks. I am trying to grow traffic to my sites and do not want to spin my wheels.
