I just have a question. Does posting in a forum improve my PR if I have the signature in my blog. Because aren't I just adding like a bunch of links to my site. So since I am posthing this thread, does that mean I'm adding another link to my site, so google likes it?
That was a question in my mind, but hope to get a real answer, here. But I think you should not be posting questions here about this forum. I think you must post at suggestions and feedback.
Although signature links pass link juice, the juice is extremely little as all of us are trying to squeeze the juice of of a page in the forum via signature links.
