Send are receive files, share forums, channels and chat, with RetroShare
RetroShare is a free without limitations program that will let you connect with friends and colleagues independently of on line platforms like Facebook in a peer to peer fashion.
The program lets you safely (using encryption) share files, send and receive messages, follow channels, chat in forums, etc.
A portable version is perfect if you use more than one computer. RetroShare’s user interface is powerful and convenient — clean, pleasant, tabbed.
A wizard guides you to connect with others, and if you need more help, you can find help in the program’s documentation.
