Thanks for the thanks, Nong, but you may like, next time you ask a question, to add your comments (and thanks, if you want) beneath the other comments, as if you're answering yourself. I've checked and I see that you asked a question about your ballerina apple tree - if you'd added this beneath that, I'd have known anyway because I'd have been notified something had been added. Anyone who answers a question or adds a comment to a thread then gets notified in this way when something extra goes on.
