I was waiting for the new site before I added the fixtures manually to my email schedule (Microsoft Exchange 2003) as I though I read there would be an export feature on the new site and there is. However it doesn't work and I get this:
This error can appear if you have attempted to save a recurring Lunar appointment in iCalendar format.
To avoid this error, set the appointment option to Gregorian instead of Lunar.
I have tried with Google Calendar and does seem to work OK.
I am sure there will be a few bugs to fix but if anybody finds a workaround please send me a PM. I can't see anywhere obvious on the site for reporting bugs/features.
