Admin prefers "TBA" for unknown cards. I don't know what the take is for cards where the name is known, but the number isn't. Putting it as NNO indicates that it should be unnumbered, when that's not the case, so I think that wouldn't be the ideal way of denoting that the number is not known. I'd send Admin a note along with the actual known info and see what the response is.
And I don't know if you typed theplayer list or if you copied it from somewhere else, but there are at least 2 names there that I noticed that are not spelled correctly.
