Yes, what Spock said. There is never a reason for anobody to put a link in their post except for when it's related to quality control, and so moderators remove URLs from posts, or at least make sure the links don't work. It's a matter of self preservation, really. I have seen people in SEO forums recommending others to come to this forum and ask about something ODP related, and slip their site's URL into the post, thus posting not for information but for increased PR. We're not particularly keen on people using the forum for that, and so most of us will shoot unnecessary URLs on sight.
