Actungbaby80,
No one in your chapter knows what the DZ letters mean?

As ritual advisor for a chapter here in Georgia, that really surprises me!
I can't tell you what the letters mean online. Even e-mail is not a safe place to send messages because they can be so easily intercepted. In fact, National HQ has told us not to send out any private Delta Zeta information via e-mail, and not to post messages with such info in chat rooms - even if they are advertised as "Delta Zeta Only" rooms.
Since I can't help you out myself, my suggestion would be to ask your CCD. If she doesn't know the answer, have your president contact National Headquarters (via telephone) to find out. This is information that every Delta Zeta should know, so please have your chapter get this issue taken care of soon!
Good luck!
DZLAM,
Carrie
