    • I've never found a desktop messaging software that works half as good and stably as Discordapp on a web browser. So much that I couldn't be bother to even try the Windows software.... I use the APP on my Droid, which is every bit as good and yet unbeatable from any other messaging service that I tried. Also excellent for rapid file and image (full quality) droppings.

    • it does everything skype does and more, including end-to-end voice and text encryption, which skype does not.
      Guest 2/4/2016
    • Jitsi is a front-end capable of using multiple protocols. Using XMPP, it can provide text, voice, video, and screen-sharing calls as Skype would. On a server with MUP enabled, it also allows groups. File sharing may be slow, but no slower than Skype. As such, Jitsi can functionally replace Skype.
