The Traditional Latin Mass Society of England and Wales, made of priests and layfolk, recommend Fish Eaters: http://www.latin-mass-society.org/links.htm (and the British SSPX linked to it at the old domain).

Contrary to the "radical" nonsense being hurled at it, the very neo-con CatholicCulture.org (formerly PetersNet.net) gives it a "cautious" rather than their "danger" label http://www.catholicculture.org/sites/site_view.cfm?recnum=1915

Jacob Michael of "Lumen Gentleman" calls it "One of the best Traditional Catholic resource sites on the Internet, period. Tons of information and research on Traditional Catholic teachings, customs, habits, prayers, and anything else you could possibly imagine." http://lumengentleman.com/index.asp

Tradition In Action links to it: http://www.traditioninaction.org/links.htm

Fr. Jim Tucker of "Dappled Things" has linked to it a number of times, Religious Tolerance.org links to it (http://www.religioustolerance.org/rcc.htm), New York University's "The Revealer" links to it and calls it "an excellent introduction to the "traditionalist" Catholic movement" (http://www.therevealer.org/archives/links_000260.php), Charles A. Coulombe likes Fish Eaters, Amy Wellborn has linked to it and even financially supported it, parishes have linked to it, Seattle Catholic has linked to it  what are you wanting? A papal bull?
