Done. Here's what I sent c/o the Principal:

I know the last thing you probably want to see is another mention of your Class Project, but I thought it would be well to forward you a link to a recent discussion it has engendered at the Mudcat Café, a website devoted to blues and folk music. The URL for the thread is

http://www.mudcat.org/thread.cfm?threadid=29482

and I am also sending the current state of the thread as an attachment in html format. I think it is important for you and other teachers to be informed of the serious concerns and irritation this sort of irresponsible educational behavior engenders in the public at large.

Sincerely yours,

Liland Brajant Ros’
