Hello,
thanks for using/evaluating Reminderfox.
Yes, it seems to be a tricky situation. You can define an repeating
event which occurs every first Sunday a month. The same for Saturday.
But if the 1st of a month is on Sunday (May 2016) that first Saturday is
on the 7th for example. There is no way to 'connect' the first Saturday
to such a rule 'if the 1st is a Sunday, then ...
The other problem here is, Reminderfox doesn't support to exclude or
change specific instances of a repeating reminder.
For your last point: Reminderfox stores the events/reminders such way
that can use that store on any supported OS. So my setup is o use the
same ICS file with a dual boot system (Linux and Windows).
Also you can share the reminders (ICS file) with sync via a remote
system like Google Calendar or (my favorit)
fruux.com. That way anyone
how has access to the remote calendar can read (and write) to the
calendar. I think with fruux you can also have a setup so only specific
users can write to it. Give it a try.
