starting out at the bottom, you might want to keep your greek affiliation to yourself depending on the region or area you live in. In some places, it could serve an advantage to you, in others, a discriminating career trap. I had mine on a resume for when i was going for internships and summer employment (who cares if they know or don't know, some of those jobs were only experience and no money). But for a real resume, post-grad career hunting, I'd leave your proud positions as Pledgemom or VP of Greek Relations out of it. Maybe re-word your activities so they are just general descriptions of a student organization. You never know what kind of job opportunities you'll miss if the interviewer hates greeks. Besides, it looks better when someone finds out later you're greek, makes your status at work a bit more respectful. Besides, getting a job because you're greek may make you appear less qualified.
Of course there are people like me who'll take anything for a dollar
