Just being nosy here
I did a search but didn't find anything relevant, please don't hate me if I missed something
Which GLOs don't allow their new members to wear letters?
AEPhi doesn't allow anybody but initiated sisters to wear letters - the Phi, at least, has to be spelled out, or you can spell out all 3 letters. The reasoning is that only initiated sisters know the meaning of the letters. Which makes it all the more special when you're initiated - I can think of at least a couple of my chapter sisters who brought letters to initiation and put them right on afterwards
But it did put the kabosh (sp?) on some cute T-shirt ideas...
