Yes, I've heard of those, and visited that website, FaithComesByHearing.com.
I tried getting set up with the Bible Ambassador program, but I'm not sure
if it's really accessible. I wrote to them about it, and someone from
technology replied, saying that he was interested in making it accessible.
I've never heard from him since. I wish there was such a thing as a
standard program or template that anyone can add to their site without much
effort to make them accessible.
