I have temporarily removed the tag board because during the upcoming holiday it will be impossible to check it for the Spam that has been accumulating there.
Meanwhile you can leave your comments - indeed I urge you to do so - by clicking on the "Comments" link at the end of this message. I suggest you choose the "Name/URL" option. Just add your name, not your e-mail address. If you choose "Anonymous" please do write your name at the end of your message.
I'll post another message about suggested homework.
Lessons start again from 26 March. See you then!
