I would love to see you develop a website to discuss your experiences and your proposals for changing the rearfacing recommendations in this country. Having a website to link to is probably a better way to spread the message then copying and pasting posts that you have made on the board.

If you could make a you-tube video, that would also be a powerful way to convince people.

Maybe talk to the Kyle David Miller foundation about how they approached the media and lawmakers and medical boards. They did a great job promoting their desire to keep kids harnessed for as long as possible and they spread the news via their you-tube video, news media, and their foundation they created. They probably would have some valuable advice on how to approach getting your message out to the public.
