This is probably the most misused term in all of the World Wide Web lexicon.
What it should mean is, "You are attempting to view an area of this website whose functionality is not quite ready for publication, and you should keep your eye out here for imminent publication of the working form of this page"
What it has come to mean, in the experience of most of the web browsing public is, rather, "This page is far from complete, and your continued expectation that it will be published with full functionality sometime within your own lifespan, or even before the end of time itself, is pretty unrealistic."
Rest assured that the former definition is more the truth for this website, and that the webmaster will likely be publishing this page quite soon. That said, don't hesitate to let him know if a page remains "under construction" for any extended period of time
