Welcome aboared, Graham.
It's sort of traditional here to set up a mini-welcome thread for each new member, so don't feel put upon! 

You asked in your first post about the relationaship of this forum to the BBC - well, many of it's contributors were, and many still are, posting on the official Radio 3 messageboards. But this site is wholly independent (and doesn't have a curfew, and has many other cool features). Hope you will feel free to chip in to the many interesting debates and also nonsense that prevail here... 

Ed: Ron got there first. Ignore this thread. (I can't delete my own topic, apparently!)
