Ho’okipa is Hawaiian for “hospitality” or “welcome” – and that’s what this is all about: be invited to register your account on the hookipa.net XMPP server and chat with your friends and family!
XMPP/Jabber is an open standard for chat and messaging, in which the users are independent of closed and commercial systems (e.g. WhatsApp). Similar to telephone, post or e-mail, With XMPP it does not matter which provider you are using to connect. Sometimes you can even use the same address as your e-mail for XMPP. And you have the free choice of tools, i.e. which apps / programs you want to use to communicate with others.
