It's junk because PHPBB is outdated and the spammers were circumventing the registration security. That should no longer be an issue; I've simply closed registration. If some day down the line it look like new people want to talk about SkyOS...well then I guess we'll cross that bridge when we come to it.
As far as closing the website, I absolutely disagree. Even if SkyOS is no longer in active development, it's a very important and interesting footnote to the world of alternative operating systems, and to close down the best resource for information about SkyOS would be no different than burning down a library.
