I’ve been using XMPP jabber for many years and it is nice to have jitsi desktop available. While I primarily use Pidgin (XMPP, Bonjour)
Jitsi Desktop fills the gap testing against dissimilar XMPP clients, & SIP.
Password protection of your accounts is great.
Most internet users are oblivious to XMPP, hopefully XMPP wont fade away like the desktop
Great job on this project
