That's true Annamil, but if Kat got their names and posted them then anyone reading this could say thay were them AND use their names. Probably a better way to ID these folk would be to mail something to Kat which YOU could ID as one of a kind, have Kat give it to them and thay could use that as a form of authentication. This could hold true for anyone wanting them to come visit with them. Maybe a letter written by you inviting them would be a good thing to identify the 'real McCoys'.
