Feel free to browse & download what you need, just don't hammer te server: This might get you banned. Use the torrent to get the full archive.
Also please note that using a tool like httrack/Webcopy/etc will probably not give you a complete archive and you'll end up with quite a lot of 404.html pages.
If you run into something that shouldn't be here, please feel free to contact me on Twitter. Also if you have files to add, please do not hesitate to contact me.
