Hello guys, I got some PR 0-4 .edu forum links. I am gonna put links in my signature. All links are do-follow and those PR is actual thread PR (not a domain PR) and I am also able to get my reply on the first page of those threads. So, basically I am getting 0-4 PR edu and Gov ******** backlinks. So I want to know are they good as they are coming from signature and how effective they are as compared to a normal .com backlinks. Thanks for the help.
