If anyone is interested in taking part, you can complete a survey about your thoughts on contact especially through technology/social media. I thought it was well designed and there are several boxes for you to write your opinions as well as tick boxes. You need to have an adopted child, but you don't need to be in contact with any of their birth relatives to do it. I had something to say about bloody FaceBook anyway!!!
