"Lost" Book of Commandments Witnesses Found

Hi all,
I just saw an interesting article at Mormontimes.com about the "lost" witnesses to the Book of Commandments being found. In the latest book on the writings of Joseph Smith, the list was published (names being "modernized" - what does that mean?). Anyway, here's the url for the article:

I wonder what Craig Criddle thinks of this? I noticed a comment by someone who had looked at the article, where the person remarks that it looks like some signatures may have been erased or something. I wonder why anyone would do anything like that? It does sort of look that way, at least from the photograph they show in the article.

Comments and/or questions?
