A simple "you forgot to include the credit and link" comment would have come across better.  Wolf doesn't plagiarize and works VERY hard to keep us informed.  He's bound to make a misstep here and there. 

I hope that doesn't sound too harsh but Wolf deserves a more considered response.  IMHO and FWIW

BTW, it was a very good article.   Thanks Wolf for posting it.

Cheers, DW
