I'm working on a guide to Spanish versification. Just for my own amusement, I'm just collecting all my observations from many years of study. I'd be glad to share it. It's written in English, since I thought it might be of interest to some who don't know Spanish well. I'd be glad to share it as an attachment with anyone interested. It's at about 3,000 words and growing. Eventually it will be on line some place. It's written in a FAQ format, so send me your questions.
