I love the concept but I think there can be more content.
It's basically just a bunch of dialogues and threads with little description on the phenomenon itself. I'm not saying it's bad but it's just not enough and not that logical. I don't think the GPD administrators will allow all these insignificant content in a "survival guide or serious document" sort of page while they indeed show great significance to the readers.
I know this concept is easy and does not require too much description. Forum thread is a great way to cover it. But I've seen plenty of excellent articles on the CN site that convey the very same idea. Actually, Memories, the CN featured level of this May, is one of them. It's bascially another document on the Frontrooms but from a different perspective, in which most of the people have forgotten about their homeland and believe that memories about the frontrooms is created by the Backrooms. It did a great job with description.
Well, I do love to see how people in the backrooms talk to each other. But I don't think it should be full of it. And there's a lot more you can do without dialogues.
In a word, great concept but execution not good enough.
By the way, I like the CSS you make in this page, especially the terminal chat one. But the forum thread…… ummm, the colors don't match the liminal theme, don't you think so?
