Several people have emailed me to ask about copyright and plagerism
issues. I found this website that does a good job of explaining it --
somehwat "legal jargony" -- but should be a good resource for finding
answers. I would bookmark this site for future reference for ongoing
questions. Hope this is of help to those of you, including me, trying to
understand the whole thing. In particular, read the section at the
beginning called "Overview" as copyright relates to ideas on the internet.
