Thanks Dave. I will pass this on to the editor. Roger D. WilsonFilm Scientist613 324 - [email protected]http://www.rogerdwilson.ca Without failure you can never achieve success. I have based my process and my career as an experimental film artist on this statement; and I welcome it as it pushes me forward as an artist to try something different, something new.
