I have heard through the grape line a ton of them are because apparently they increased the quotas for all the sororities and that's why we have to register for recruitment this time around unlike in the past because they understand there will be a higher volume. Also, from what I have heard, the sororities are having a hard time getting dates because they are trying not to have too much overlap because so many sororities are doing the informal recruitment this year and will be able to accept more girls then in the past.
Now I am not, obviously, a part of panhell and therefore don't know the inner workings but this is what I have picked up from friends in greek life.

It is total that would have been increased. Quota is never set or established until the amount of women going through recruitment is determined after several rounds.

They are minus one sorority now, but I don't think they want to add another one, so I'm sure that has something to do with it.

Haha sorry I'm not greek obviously so I don't know the exact terminology but I heard stuff about the total being increased before tri-delta was gone.

Huh, that's weird. But good!! Raising total means the majority of the chapters are healthy.

Yeah I also heard that total was raised before TriDelt left... but then again, not yet a part of NPC so I don't know for sure

Total was raised before Tri Delta left campus. Some people were confused about the choice, as some sororities were not at total and had not been for some time, however it did sort of even out Tri Delta leaving (though I am still very sad to see such a strong national group go).

Basically almost every sorority will be doing spring recruitment, except for those that quota put them over total (previously 90 women) from fall recruitment. And even then they would have to be at 95 women total. So yes, most of them will be participating. Hopefully the dates will all be up soon, I know a lot of people are wondering about them.

dateeeeesssssss?????? seriously

I want to join a sorority this spring at penn state but I am unaware how to do so. When and how will I find out more information?

A good place to start is to actually contact the Greek Life office.
I'd call rather than email.

That would be grapevine. ;)
