Is it simply that the person who sent him the e-mail didn't provide a link as to where the statement came from?
Sender provided no link. Also a background concern about hackers and viruses/virii on her website exists despite huge efforts to keep it clean. From time to time they get through and taint it.
Since Alan’s purpose is to get the information across, and you can see he supports her efforts to get at the truth, there is no intent to minimise her efforts.
I am not sure what the “@alanPeters” is since he does not have any social network memberships which generally use this kind of reference. ???
