I'm working on an intranet website for which I need personal user calendars. I'm looking for a plugin with which users can create completely private calendars or a plugin that shows only their own events. Something that is very Google Calendar-like or a very smart way to integrate Google Calendar (so things can be edited within WordPress). I've been searching everywhere and tested several plugins, but up till now none of them seem to support this without having to code it yourself.
I would really appreciate any suggestions!
