Back in the day, when quite a few folks were participating, it did make sense to have CBN. I have posted on CBN when I didn't feel comfortable posting on CC. However, since participation has dwindled, I think it probably makes sense to combine them. As Bob said, professionals were reading and responding to posts on CBN, and I think that cellists are cellists, no matter how that is manifested in the life of each individual. However, I will admit that I have come to this opinion only recently, after 10 years of playing and a lot of contact with professional musicians through my volunteer work. Some warning probably would have been good, as change is sometimes difficult, even if it's for the better.
