I'm a bit of a Meetup junkie so I'd like to automate the appearance of any Meetup I RSVP to automagically appear on my Google Calendar.
Yes. Here's how:
When you login to Meetup.com, on the top right, under Your Meetup calendar, you should see an Export link.
After clicking on it, you should see All my Meetups and My Yes/Maybe RSVPs.
Click on the Google Calendar icon under either of these, 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 My Meetups as a subscription.
