Guild Calendar
Guild happenings, AQW releases and Ravens birthdays.
Add this link once and Ravens events sit beside your own in Google Calendar, Apple Calendar or Outlook. Your app re-checks it every few hours, so anything new turns up on its own.
This link carries the public calendar: guild events, AQW releases and birthdays.
Members-only events are not in the public link. This one is yours alone and includes them.
Keep it to yourself: anyone with it reads your view of the calendar. Replacing it stops the old one working.
