I don't want to cause a huge thing, but I have to know does the Spotted Draft registry have a closed stud book? There is a situation going on (it's quite along story) and this one person is saying that they are all grades because it's doesn't have a closed stud book and all this stuff. I'm not so sure on this as a couple people have said they are a breed and recognized and what not. However I wanted to see what others know. Can you help me sort this out?
