I hope you realize how retriscting this is and how this would affect and could discourage newbies who are new here that actually want to learn, ask something, share information, warn people, etc... restricting them to not be able to post links is just too much(at least for me).

anyway, I remember similar point(newbies should not be allowed to post links) has been made in the past and I gave the same sentiment I am giving now.
