Dear Optics/Photonics Professional,
If you are reading this text, then I commend you for being very tricky! You do not need to add a SPIE ID, as long as your email is in the box above. But our system requires it. I've added this text to move it further down the page. I hope we get your communication preferences all straightened out. Have a great day!
