Oh yeah, I know, it's been a long time. 
The website WILL be back, eventually. Actually it's just been upgraded to the latest version.

When will it be back? The only thing I can say is: soon, but I don't know when.
In the meantime you can visit another great retro forum, called RetroForum. It is fully in Dutch though.

Retroforum 

Don't stop looking here, we'll be back. You can still make your account if you want to, you'll receive an e-mail update when the site is online.
Thanks for your patience.
