Yes! The “Get your friends in” share link lets anyone not already on Surkus sign up and respond “yes” to the event you’ve been invited to immediately. The “Get your friends in” link also adds them as your friend on Surkus and puts them at the top of your friends invite list, so you can see that they’re going.
The regular share link on the main event page lets you share the event with others who aren’t on Surkus that you think would like the event. If they sign up, they won’t be added as your friend (so use this link if you’re promoting an event to a bunch of social media followers you don’t know)!
