Yep, Malcolm. I also wonder how many mistakes there are in the music. There doesn't seem to be any review at all. The tunes get posted and immediatly sent off with no check for quality.

I put the ones I do on the website for review and comments because I'm very aware I can make mistakes. I've received almost no formal education in music, and "self taught" means there are huge gaps in my knowledge. I can also mishear something that another person would pick up.
