Since 2006, bittorrent sharing has been the primary means for users to trade software, music, movies, and digital books online.
This lawsuit risk is a reality, and you must accept this risk if you choose to download P2P files.
If you do use a hardware router or firewall (which is a smart way to configure your home machine), you are likely to get "NAT" error messages at first.
This is because your router/firewall has not been taught to "trust" your bittorrent data yet.
And indeed, its popularity has taken off since 2005.
The torrent community has now grown to millions of users worldwide in 2009.
