For those wanting to improve their penmanship I can suggest, Kate Gladstone. I have used her and have improved my handwriting. Also, the book Write Now is a great practice workbook. http://handwritingrepair.info/ is Kate's website. The book is by another person. I have the book, but haven't practiced it in some time.
This site actually seems very good and very practical. Most handwriting sites I find seem very oriented toward teaching a particular style, often italic. This site seems more directed to helping make what what one is starting with more legible and prettier.
