This year as an online event, fully powered by self-hosted free and open source software (i. e. no Zoom & Co). Free as in free beer!
The offical CMS Garden conference is an UnConference or BarCamp: Any session (prepared or spontaneously) will be announced informally. You may announce your topic wishlist as well. Usually there will be someone willing to hold a lecture on it. We know from many common activities that it need no more organization than this for a fertile sharing of expertise. Let yourself be inspired, educated, enthused!
This year will be different because of known reasons: It will be an online barcamp. Stay tuned for detailed information!
