I subscribed to Karen's newsletter. Any one else that did, will or probably already has received an email through the newsletter subscription on Karen's passing.
Reply from Fred Langa after Fred received an email from her brother Bill:
RIP Karen Kenworthy - Fred's posterous
Karen Kenworthy wrote a very popular column for Windows Magazine, when I was there. She was as good a programmer (I still use some of her "Karenware" software today) as she was a wordsmith (her readers loved her stuff). I have none but positive memories of working with Karen.
There is a link to Karen's obituary in Bill's original email to Fred.
