i really would like to test or use this plugin. however, when i try to use the shortcode in either [largecalendar] or [iCal http://mycalendar.ics i get an "Invalid URL" error.
the link to my ical feed is in the screenshot as well. also, is there a problem in using a webcal feed from microsoft? as the address starts with "webcal://" instead of http but even the other plugins i've tried using have no problem with it as they either change the prefix automatically to "http://" or they allow me to change it to "http://" and it work.
