Welcome to Wikipedia, and thank you for your contributions. Although everyone is welcome to contribute constructively to the encyclopedia, please note that there is a Manual of Style that should be followed to maintain a consistent, encyclopedic appearance. Deviating from this style, as you did in Photoreceptor, disturbs uniformity among articles and may cause readability or accessibility problems. Please take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you. Kkmurray (talk) 23:43, 21 March 2013 (UTC)[reply]
