Though I do not have the documents with me, the one transfer per year rule is stated in more than one document. One thing to understand is that the one-transfer rule is limited in application. It only applies to the actual transfer of points from one member to another. It does not apply to a member who uses his points to make a reservation for another member or person; for example if you rent to another member and you do the reservation using your points and putting the reservation in the other's name, that is not covered by the one-transfer rule as you have not actually transferred points from your account to the account of the other member, and you can make ressies for another using your points as many times of year as you want.
