I just noticed that org-diary-class is not suppoerte in ical export Carsten told me that sexps are not supported by org But I have a problem now! I tried 3 ways to generate a work that repeats each 3 days. ***** Appt: Work <2010-02-01 Seg 18:15-18:30 +3d> ***** 18:15-18:30 Appt: Work <2010-02-01 Seg +3d> ***** Appt: Work %%(diary-cyclic 3 1 2 2010) 6:30pm Appt: Work All of them appear in Agenda View but none appears in the .ics file Is there a way to "design around" this limitation? It is quite important to me now that I am using gcaldaemon http://sourceforge.net/projects/gcaldaemon to sync my Google calendar files Daniel
