After you’ve created your event you’ll see the Invite button on the right. Before clicking that, open the Chrome Web Store (or Firefox Plugins Store) and search “Invite All For Facebook.” Scroll down, you’ll the extension called Invite All (for Facebook). There are a couple other extensions there, if Invite All (for Facebook) doesn’t work for you for whatever reason (it should), try the other 2 to see if either of them work. Click Add To Chrome and then click Add in the popup. The extension is installed immediately. Go back to your Facebook event, click Invite, you’ll see all your friends with a new button to Select All – click it all your friends will be added to the list to be invited to your event. When you’re ready to invite all friends to your event, click Send Invites. Your invite will now be sent to all your Facebook friends immediately.
