I've started a little website over at thefightobserver.com and would love for you to check it out. One of the first features I've implemented is a Combat Calendar that allows you to subscribe with Google Calendar, iCal, Outlook..etc.
I know that it's something that some have asked about in the past and since there wasn't any I could find on the internet, I built one myself. http://www.thefightobserver.com/calendar.
Any feedback would be appreciated. If you would be interested in joining me on the site as a writer or calendar curator I'd love to hear from you.
