Hi, my apologies for being slightly off topic, but I guess this might be interesting to see some of you / related to some topics discussed on this list. Please feel also free to forward this to anybody you might have in mind, who is dealing with novel calendaring solutions and ideas and might be interested in community discussion. Thanks and best, Hans-Joerg ----- CalendarFest is a novel (virtual) event, which wants to let users and developers of (electronic) calendar applications, servers, and related groupware systems, share experiences and discuss novel ideas. CalendarFest will take place *18th of October*, 02:30h PM UTC virtually via Zoom, and is held in conjunction with the CalConnect virtual conference <https://www.calconnect.org/events/calconnect-virtual-conference-autumn-2021>.
