You're welcome, buze.
Just wanted to mention, for anyone who's interested, that I've reorganized my gum site and added some new things (a page on tonality in gum, a page on development, a few small pages on troubleshooting--- these are all available as links from "process notes." I've also added information on tricolor printing, and reorganized the galleries and relinked them into the site (they've not been accessible for at least two years, since I tore the site apart in preparation for a major revision, and haven't been able to get back to it til now.
