If, as is my guess,

* FlyerTalk (Randy) doesn't really mind to let us regular amateurs 'exchange' certificates without looking for 'professional' profit on this board,

* but on the other hand, Randy (with his links/interests/relations with airlines, ff-programs) doesn't want to make official statements regarding this subject (understandibly doesn't want to officially upset the airline industry)

I wouldn't go on asking for his oppinion here - I simply thank him and FlyerTalk for the tolerance on this subject.
