Yvonne, I have edited your post on Iolo Morganwg and the Coelbren Alphabet to include the source web link for the quote you shared.
The subject of the Coelbren Alphabet is a large one, and deserves its own dedicated discussion thread, which is why I have taken yours and Manu’s posts on the topic and placed them here: http://culdiantrust.org/culdianforums/index.php?topic=299.0
Further discussion on the Coelbren Alphabet in its relation to the Kolbrin or Iolo Morganwg should be replied to there, unless it is directly pertinent to Yvonne’s article.
