You're right. That is standard for a text box. But the email field, which is a textarea element looks like a text input field, where pressing enter would normally submit the form.
Around 3 years ago I was living in Auckland and wanted to escape the city for winter. Hearing people moan about the weather and cold was getting boring and bringing me down. A friend told me about a town called Wanaka and it sounded like a fun place so off I went. It was the best decision I've made yet. Even the police are friendly here. For example I once ran out of gas and while parked on the side of the road a cop pulled over and gave me a ride to the gas station and back. During the ride he told me how much he loved his job. I've found my new home.
