AAMDirect II

A.A.M Direct (formerly NNTP A.A.M Client) is a type of email system whereby two or more people can communicate privately and/or anonymously with strong encryption . It uses the alt.anonymous.messages news group and does not require a usual email address setup. Messages are sent to the news group directly or through the Tor network. Note: If you have AAMDirect II already installed, just download the AAMDirect.exe and replace the old executable. Rename the old executable first and test the new before deleting the old. See WIKI for updates and changes.
