I recently enrolled in the DC and received the 800 points.  Are these points legacy points or are they trust points?  If I need to rent additional points to supplement a reservation which type of points would I need to rent or does it matter?

The 800 points that you received for enrolling are a third type of point -- they are Plus Points.  Plus Points behave just like legacy points except that you can not transfer them to a third party.  You can combine them with points that you have rented and there have been many reports of people combining legacy points with their Plus Points. I assume they would also combine with Trust Points, but we haven't seen that reported. Best, Greg
