If you use Foursquare to check-in before your movie going experience, then do we have some good news for you! Our friends over at Faceless MegaCorp have created a Foursquare plug-in that will alert you if there is anything to see during or after the credits after you check-in!
Follow the link above to find instructions for installing it. Once you allow the app for your Foursquare account it should automatically notify you at check-in if you should stick around or not. See the screenshot below to see it in action! (oh yeah, in my experience, it might not show right away, you might have to press the refresh button on the top right to get it to come up if it doesn’t right away)
I’ve been in contact with the developer and the app is still in it’s infancy. He plans on adding more features soon!
