We have probably all had comments sent to us, concerning a particular authors opinion on the genealogy of the profiles we manage. However, given that most of the members are unlikely to own copies of these publications, how are they to verify that data ? Are we expected to simply accept it because somebody said so, or do we treat it as speculation, or at best third hand hearsay. If we cannot personally check those sources, are they any better than a comment overheard in the local pub ?
