rosali, thanks for the reply, and the great plugin.
I read a previous post where they spoke of the using the RC as the "server" and running DaviCAL on the same box, to allow calDAV clients to connect. I assume they meant that the calendar plugin and DaviCAL would be accessing the same database. The specs for DaviCAL tell me that database would have to be postgresql. My current roundcube database is in mysql. Is there another calDAV server worth using that could run on FreeBSD and use mysql? fyi, I've explored using gmail as a backend and do not consider it appropriate for my situation, but I can see it as practical for those with very few users.
I'm still learning here, but I'd rather not put my efforts (and spare time) toward a waste of time. Is this worth doing, or should I put my efforts toward helping with a calDAV backend for the plugin? I'd appreciate some advice on what calDAV server would best suit, or if I should give up for now.
Thanks, Dave
