I have a question that is in regards to someone who used to be a member of another fratertnity. We have a guy that is pledging in the spring that is a pretty cool kid a friends with most of us. He was up front that he was in another fraternity and showed us documentation that he is no longer a member. It goes something like this your name and address has been removed from our membership files. Good luck in your future endeavors. Now I know that just dissafiliating wouldnt allow him to pledge but but he left nationals as well so I would say he is legal. Anyone have any imput??
