Please note that I always look at questions in 'Ask a Teacher' before I look at my private or visitor messages. If you have a question to which you would like an answer, I'll answer it more quickly in the public forum. If I don't answer it there it is because:
1. Somebody else has already given a satisfactory answer.
2. I don't know the answer.
Please note, also, that I feel flattered when I receive the occasional friendship request, but I have to decline. I have no wish to offend anybody, but I am not a believer in forum friendships.
