Freenet is free software which lets you anonymously share files, browse and publish "freesites" (web sites accessible only through Freenet) and chat on forums, without fear of censorship. Freenet is decentralised to make it less vulnerable to attack, and if used in "darknet" mode, where users only connect to their friends, is very difficult to detect. Share files, chat on forums, browse and publish, anonymously and without fear of blocking or censorship! Then connect to your friends for even better security! "
