sabnzbd is a piece of software which fits right into your internet explorer (like Chrome or IE) just like uTorrent. You also need a paid subscription to a usenet server (like Astraweb). It's about 10x as fast as torrents and much less danger of being caught since it isn't peer to peer it's peer to web host.
I fuckin hate utorrent and bittorrent... this shit (SABnzbd) ownz!@!
