I'll copy here a portion of my talk page notification, several months ago:
There has been no response to this post. This article is significantly lacking in references, and is not up to FA standards. Dana boomer (talk) 19:02, 7 September 2013 (UTC)[reply]
I am on the notification list for some reason but I have no opinion one way or the other as to whether this article should be featured or not. I believe it WAS featured several years ago. The author of most of this article is CJLL Wright (https://en.wikipedia.org/wiki/User_talk:CJLL_Wright), who has not been active on Wikipedia for more than a year, at least under this name. He may still be around and would be worth contacting. My own research into Morley is focused only on his relationship to Chichen Itza and those sections are as accurate as far as my knowledge goes.
