iCal won't stop adding meetup.com events
Tonight iCal suddenly started adding a TON of meetup.com events from forever ago. If I click cancel, the "Add Event" box pops up again and asks me to select a calendar to add it to. The cancel button doesn't seem to work. IF I click ok, iCal proceeds to add that event and then goes on to add another and another and another and so on even if I don't actually click "Ok" after that first time. My calendar is FILLED now with events that I did not ask to be added... I haven't even logged in to meetup.com in months nor have I even read a single meetup.com email. I have NO idea why this would have started. I DO know that it started immediately after I closed an alert that popped up about an event that I had manually entered that had nothing to do with meetup.com.
I've tried all that I can think of including revoking iphone access on meetup.com as well as deleting my meetup.com account entirely. iCal still tries to add all of these events. How can I get it to stop? iCal is now pretty much useless as my calendar is filled with crap and any events/dates that I do need to keep are lost in the sea of meetup.com crap. The only way around it that I can see is to allow the events to all be added and then delete them all manually. Please help... why on earth would this happen?
