Love your sites! They are very well done. I'm curious as to how you are creating the fonts. Did you use a programming library or did you dig into the font format specifications yourself?
Also, this is just a minor suggestion, but I would love to be able to map a non-standard character (such as the copyright symbol) to my signature.
That was what we did first. But a lot of people asked us to bring back myscriptfont.com because they did not understand this "create template" stuff .....
