As for how long it takes, it could be anywhere from a year to 4, 5, 10 years. It depends on the campus's need for more sororities.
Your best bet is still to talk to your school's Greek life office.
After that, you could also call the sorority's national/international headquarters and talk to someone there, but don't be surprised if they decline to talk to you.
Another tack would be to form a local sorority...maybe with the hopes of one day affiliating with a national. That's still going to take a long time to set up, and even longer - years, possibly - to affiliate with a national.
Again, talk to your Greek life office to see what the needs are and how you'd go about creating a new organization.

LOL.

Now don't you think if I wanted it to be obvious what organization I was a part of that I would have just said so? :rolleyes:

For starters people on GC who won't name their organization but make strong statements about Greek life or their chapter make me suspect. Just how it is after the years.

Aside from that, if you feel so strongly against your organizations philanthropy and for a good reason (how funds are spent, something I too look for and place importance in) I don't get why you want a hush hush secret.

Also a majority of the NPC organizations are involved in/with various large and well know organizations, so if one of them is so terrible I'm curious to know what it is.

I don't know that I disagree with Ramsey. There's one NPC sorority I can think of where I don't believe in how funds are spent from the national philanthropy. I would be upset and steer clear of that group as well if I were a super smart 18 year old who knew better, that group was at my university, etc.... Since the group wasn't at my school, it wasn't an issue, and I'm pretty sure the specific partnership has changed since I became greek anyway
