[Remind-Fans] stopping a recurring reminder forever, at a certain point

[Dieter Plaetinck]

Hi,
I used to have an event every monday evening (with some exceptions) like so:
PUSH
        OMIT May 16 2011
        OMIT Jun 06 2011
        OMIT Jun 27 2011
        REM Mon AT 19:00 DUR 4:00 SKIP MSG %"band rehearsal%" %1%
POP

however, from monday january 9 2012, and onwards, this event has stopped.
How do I put an enddate on a recurring event?

Dieter
