I recommend the delightful Eats, Shoots and Leaves by Lynne Truss to anyone who wants to explore the joys and wonders of English punctuation.
Going way off topic here, but I'd certainly support Joe's recommendation. It's hard to imagine a book on spelling, punctuation and grammar reducing one to tears of laughter, but "Pansy's ready" did it for me
And 2amageing, I really appreciate the new style. I have to admit, I had taken to skipping over all of your posts, as they were too much effort to read. I'm sure that was my loss, but your new style makes much more comfortable reading
