If you’re used to leveraging Facebook to coordinate events, or if you’re an event promoter who has started using Google Plus, you might be scratching your head on how you can manage events on Google+. Google+ doesn’t have a baked in events functionality yet. However, it’s still pretty easy to create events and then invite your Google+ circles to them, or even make them public for the world to see.
This is a hack method at best… but until a full fledged API is released for GooglePlus this seems to be the best(only?) method for integrated GCal and GPlus events.
