How do I contact Tech Republic?

If I want to let TR know about a broken link or some other error/issue in something they publish (which happens all too often) or otherwise communicate about their operation (i.e. not simply reply to an article / participate in discussions, blogs, etc.) and actually expect a TR staff person to read it and respond (preferably all by regular e-mail), I see no way to do that. TR has consistently cut their support of getting and responding to feedback from their users (or at least the visibility of that function) until now it seems entirely gone. Is this actually intentional? If not, they need to fix it. If yes, this is the beginning of the end of their viability.
