Along the same lines, I have found a lot of material on Tengwar writing dating from around 2003-2004, and after that, zilch. The resource I found which seems the most extensive and thorough is the Tengwar Textbook, by Chris McKay, dated April 2004. But I've looked around for later writing from McKay, and have found nothing. It's like he vanished or totally lost interest in Tengwar after 2004.
No one here knows anything about this?
