First to DST Love re pledge class names:
They can be named according to pledge semester (Spring 85, Fall 92)
Or they can be named according to order of pledge class, whether it's by numbers (30th, etc) or Alpha, Beta, etc.

In addition to my social sorority I am also a member of Alpha Phi Omega National Service Fraternity. While we do have social aspects, our main and FIRST focus is service. Each member must do a certain amount of service hours per semester. I would be lying if I said it was as deep a connection as I have with my sorority sisters - but I didn't live with my APO brothers, and I think it does make a difference. It is a wonderful way to get into helping the campus and community.

OK, I hope these service orgs mixing with the fraternities are all girl??

That irks me too, not just as a sorority member, but as a member of a service org. We occasionally had people in APO who wanted to make it more "Greek" - as a matter of fact, I came back a few years after graduation and APO was PARTICIPATING (not refereeing) in Greek Week. I about $h!t. If you are in APO and you want to be in a social org - nothing's stopping you - go pledge, you can do both, but don't turn an apple into an orange.
