Dale says: "Chiff & Fipple is an international Internet-based information resource for musicians playing tinwhistle. Since 1998, we have operated large message board forums devoted to the whistle, the Irish bagpipes, wooden flute, Native American flute and other instruments. Our forums have over 5000 registered members. Apart from some revenue related to the placement of Google ads, used to pay expenses, these are not commercial enterprises. This is a service to musicians by musicians. To see some of our music forums, visit here.
"Commercial posts are restricted, although we do allow instrument builders and others to make limited posts regarding availability of products and services, within certain guidelines." Link
