Stop the Meetup calendar syncing with the Google Calendar

Yes. Here's how:

When you are logged in, on the right side of the home page at www.meetup.com, underneath the calendar widget, you should see an Export link.

After clicking on it, click the Google calendar link in the drop down, and it should bring up your Google Calendar page with a popup asking: Do you want to add this calendar?

Click the button: Yes, add this calendar, and you are now added your Meetup subscription to your Google Calendar.

You should then see all meetups you are attending as a subscription.

Note that your new Meetup/Google calendar will not be updated by Meetup to reflect edited or cancelled events, or if you change your rsvp, and there is no way to remove such events from that calendar.

I found if I go to:

Calender> I'm Going

you can scroll through monthly and see what events you RSVP'd "yes" to.

I then went through the events I attended and tagged myself in photos so on my profile I had photos of events I attended.
