Organ Donation

I've been asked more than once to discuss organ donation. This isn't the post in which I will. But I do want to point out the long list of rabbis that the Halachic Organ Donor Society. Three interesting things to note:

Not one member of the RCA's halacha committee is on the list and at least one person on the list is a JTS graduate and the associate rabbi of a Conservative synagogue. Also, no Tendlers are on the list. Can anyone explain that?
