Hi, we are working on a free software (AGPL v3+) multi-purpose multi-frontends XMPP tools, and as I'm in Wien this week we have asked to come to show a little demo of it. This will be tomorrow at 20:30 at the library. We have started a wiki page: https://metalab.at/wiki/Salut_a_Toi_Introduction . You can also have a look to our webpage (http://salut-a-toi.org). So if you are interested in decentralization, communication, social networks, or XMPP you can come to talk :). Thanks to SvenG and Peter for helping us with such a short notice. Cheers Goffi
