There is something behind that door.

 * The fact that eight years' worth of members attempting, collaborating, discussing, and ultimately failing probably means that there is no way to get in, but it doesn't have to mean there's nothing there...for all we know, there is coding that would kick in if one were to actually enter, and only the game's creators know what it is. (Actually, from what I remember about the TNT of that era, it's surprisingly plausible...and you can just bet they're still giggling over their little secret...)
