I am sorry to let you know that ̉DonÓ passed away from a heart attack on 7 October, 2002 while on a business trip in the UK. He is survived by his wife and two children.
I talked to his wife yesterday (24 May, 2003) and she said that she wanted to apologize to everyone for not following up on his web site and letting people know of his passing. She will have someone take over the site and respond to all of the e-mails. She will then have a small tribute with a photograph of Don and will post it on this web site.
