I don't believe GLO's should ever have t make their ritual public. I don't believe people should reveal their own rituals either. If somebody that is not a member of my fraternity some how learned my ritual and and used it for research purposes only I have no problem.
This is an interesting article I found on how TKE feels about the issue...
