The link comes up with an empty angelfire page. I do have some information on the Oera Linda book, if that helps...
The Oera Linda book was a forgery of what purported to be an old Frisian Chronicle, proving the origin of the world, and of monotheism to be frisian and dating the beginnings of Frisian culture at 4000 BC.
How someone would want to base a cult on this is beyond me.
