As far as the letter thing, you can't tell the pledges in most NPC groups they are NOT allowed to wear letters...however, if "campus culture" frowns on pledges wearing letters, you really can't force them TO wear them. That would be hazing as well. It's like frilly rush - no one wants to be the first one to stop and whatever the more popular groups do will be followed by the rest of the campus.
