I'm working on a "private" website for a group of friends, and one feature we want is a shared calendar. Now, I don't mind if people outside of the "friends" group browse the site, but I don't want the calendar visible to anyone else. I've installed the glCalendar plugin, disabled the built-in calendar, but I can't seem to find a way to hide the calendar from anyone but those in the "friends" group.
I have found a reference to SEC_hasRights('glcalendar.view') in geeklog/plugins/glcalendar/functions.inc, but it's commented out. I can't find this permission anywhere else in the fileset. What would it take to activate this so I can limit the calendar as my group wants it?
