stuckinarut2 : just download it and it will install itself in a file called "tor browser" on your desktop. Then click on that file and then click "start tor browser" and you're in with a fake ip address.
FatFreek2005 : in fact Tor works well in general, but it's not perfect. However, an organization like the watchtower cannot do anything about it. The US government can probably spy on us throught Tor, since it is behind its creation.
