Interesting, learn something new every day!
And P.S. I DID do my research and looked on your national website before asking! (Very nice website by the way, I loved reading the story about the founding of the fraternity
)
Another question:
Has APO been using a handsign from the beginning, or is it a more recent thing? (After reading some of the website, my guess would be from the beginning, but I wasn't sure).
If I'm asking anything that is not public domain, feel free to let me know.
