In order to get help from someone you have to post your SOS Code. It's a very long code. Someone else would input that code into their game and get a mission to rescue you; upon completing that mission they'd get an A-OK Code that's just as long. They'd post it here, you'd enter it into your game and be rescued. You can then create a Thank-You Code that your rescuer can enter into their game to be rewarded with extra Rescue Points and, should you choose, a useful item.
