In her AYS Virtual Assistant blog, Nora Rubinoff mentions a cool service she's discovered - it's a website called Fontifier that can turn your own handwriting into a font.
Direct marketers have long used handwriting fonts to add a personalized look to mailings, and this would be a neat way to do that both in direct mail pieces - and for short comments that you could set up as images on the web, too.
Check out Nora's blog for other uses and more information about Fontifier.
