Hi Melissa and everyone else!!!
I have wondered this for so long. See, as a member of Sigma Kappa we are taught that Sigma Kappa is today what it was from the beginning...a sorority. We were founded two days earlier than Gamma Phi Beta. Regardless though, the term "sorority" was supposedly not coined for some years later. Therefore, it's a little confusing for some of us Sigma Kappas who were taught the aforementioned. I always assumed this was brought to our attention since so many sororities today, were once known as fraternities. Therefore, it's one thing that sets us apart from the other sororities.
Just my thoughts...
LIS,
