Hey all, First, I just want to say thanks to all of you who read, and email here frequently. So "Thanks". Second, I have a little pet project.

Dear List, One persistent feedback I am getting to people who are newly introduced to R ( especially in this cost cutting recession) is - 1) The website looks a bit old.
