There are lots of sites like this, and all they do is give you links to the current (FREE) p2p network programs and some rubiish text/html guides as to how to use them "legally".

1: Go to
http://www.limewire.com and download the free version.
2: Only download non-copyrighted material.

Personally I think "3" is a load of bullsh*t. You should NOT download copyrighted material and it IS illegal, regardless of whether or not you then share it with other people.
