Here are the settings that are working for me to allow public access to my webcalendar for some events. WebCalendar 1.0.4.
I’m still having problems with both public entries being duplicated when both Darrell and Public are participants. This does not occur on a test site that I have, but the live site shows this. Currently I can get around this by only having one participant [public access] for public items. Not sure why the test site shows only one entry and the live site shows two.
