I would recommend adding in the settings, a note of the RSS or the ical feed.
I literally spent 2 hours searching for this and got 1 click away from buying another company’s product. One final attempt found one post about the default ical link is /events/ical
I would highly recommend adding a note to the settings tab to make it easy for people to find.
Keep up the great work – now that I know you have this ability I will be purchasing a few copies.
