GLOs that don't let new members wear letters?

[Betarulz!]

I know that there is some variance among chapters even.

Here at Nebraska, we as pledges were allowed to where letters, with encouragement if it was something that reflected well on the house (philanthropy or the like). But there were certain words that we couldn't say out of respect to the brothers unless they were in a song. And obviously we weren't allowed to use the letter closer.

I know that at Kansas, the Betas there rarely wear letters, even the initiated brothers. They also refer to themselves as Alpha Nu (their chapter name) rather than Beta. Also they don't have letters anywhere on their house so that you know it's a beta house. They have a lot of weird rules, that I don't think I could agree with, and I know that if I had gone to KU I would have joined a different house. I really have no idea about why...
