@drjhones, welcome to Mayo Clinic Connect. I noticed that you wished to post a URL to a web resource with your post. You will be able to add URLs to your posts in a few days. There is a brief period where new members can't post links. We do this to deter spammers and keep the community safe. Clearly the link you wanted to post is not spam. I added the link to the Children's Cardiomyopathy Foundation to your post.

@drjhones, do you have a child with hypertrophic cardiomyopathy?
