The WebCal publish feature is very useful for getting our PD schedules into our calendars. But each event is marked as “busy” (the default) which means that my calendar program (GMail) thinks everything is a conflict.
Events should be marked as “Free” .
I’m no webcal expert, but it appears that TRANSP:TRANSPARENT
would do the job.
