Nor to me.  I use two reminders for this kind of thing.  It probably
is possible to do it all-in-one, but I doubt the result would be
easy to read... actually, thinking about it, this should work for
the second and fourth Wednesday:

REM Wed SATISFY [(day(trigdate()) >= 8 && day(trigdate()) < 15) || (day(trigdate()) >= 22 &&
day(trigdate()) < 29)] MSG Second-and-Fourth Wednesday

Told you it would be ugly.

I started Remind in 1989, and it kind of accreted features.  So yes, the
language is a bit of a mess.  One day, I'll clean it up.
