** I checked the settings, no one has permission to the default calendar. **
I have no idea why your installation would work different than mine. On mine if the user doesn't have 'View' permissions for the default (or any other) calendar, than that calendar is not displayed as a choice on the Select Calendar screen.
** Everyone still has to choose the calendar before they can proceed. **
There will *always* be the 'select calendar' screen whether they have only one choice or not... but that screen should only show calendar(s) they have permission to view. The only way to get totally away for the 'select calendar' screen is by using the plug-in I mentioned previously.
