We do ask for a little bit of personal info but that is all stored securely on our servers and is used only to contact you for confirmation of your entry and with news of your success or failure if you're entering a scarecrow. If you're entering a scarecrow there is the option to opt out of appearing on the trail if you wish. The trail is designed to show the location (so please include your address and postcode) of your scarecrows allowing people to wander round the area and admire the handiwork. It will appear after judging.
We've got some guidelines on taking good photos here.
