"About Demons" -- publication date?

I've been asked about the publication date and the last-modified date of my page About Demons.

Unfortunately, I did not keep track of the date that I first uploaded it. So the publication date will just have to be 2003. The earliest version in the Internet Archives is dated Febrary 10, 2004.

The last-modified date is much easier for me to ascertain -- April 22, 2009.
