display multiple google calendars together

Hi

it should be possible, as long as they are public

I figured that, but need to know how.

okay, I think you need to add the calendar first to your calendars, by subscribing them – then, from your global Google Calendar app page, there’s a list of calendars on the left column; if you hover with the mouse on each, there’s a ‘dropdown’ arrow. If you click that you can get to the individual calendar setting. If you open the calendar setting page, there is shown in the middle a calendar ID. Copy and paste that in a feed you are creating with this plugin. Let me know if it works out.
