Each lesson usually falls into two sessions:

(1) A mini-lecture from me, including examples and a few points for you to consider. Often, I’ll ask a question and you will be able to “click ’n’ link” to compare your answer with mine. Where you see the word ANSWER written in bold caps and underscored in red, just let your cursor hover on it for a few seconds and all will be revealed by magic. (Go back to the word “ANSWER” and try it now.)

(2) A story for you to sub-edit, with a PRINTER-FRIENDLY version available.
