If you are installing a 4th or even more Raspberry Pi based feeders, you would need us to create those sharing keys for you. You are in general able to register 3 feeds yourself under the same account but for more, you would need to send us the following to create more keys for you:
1. Email address
2. Coordinates in decimal format
You can also register the third, fourth and more feeds under a separate email address and then simply email us to move them to your primary account. This works as well.
