Well this thread has just made my day 10 times better. I'm very glad I found it!
Alpha Chi Omega - I love the music connections in your founding, music is so important! And of course, Christmas is my favorite holiday, so I LOVE the colors! I also read about why they chose the letters Alpha, Chi, and Omega, very interesting!
Alpha Delta Pi - A very strong southern sorority! A good friend of mine was an ADPi and she is such a lovely woman, and I really watched her grow through her sorority. I also like the motto "We live for each other"
Alpha Epsilon Phi - I love the "Many Hearts, One Purpose" motto, it really shows unity! And I absolutely love love LOVE that you're involved in Pediatric AIDS, it's just SO important!
Alpha Gamma Delta - It seems like y'all really encourage education, and I like that! The squirrel is just so cute too. I knew a woman who was an AGD and she was just the most adorable girl, and she truly loved her sisters!
Alpha Omicron Pi - One of my closest friends is an AOPi and she has maybe the best sense of humor of anyone I've ever met! I think it's very unique that you don't have a crest or shield. You can really hold your own.
Alpha Phi - My cousin is an Alpha Phi! I really watched her go from a shy unsure college freshman to one of the most admirable women I know. Lily-of-the-valleys are so lovely!
Alpha Sigma Alpha - We were founded at the same place! I love the symbol of the Phoenix - rising from the ashes. Very touching, and something that anyone that's faced adversity should aim for. I also like that you have exemplars, it's a very unique idea!
Alpha Sigma Tau - Habitat for Humanity is a great philanthropy, especially in light of recent events. I have never met an AST but I certainly would like to!
Alpha Xi Delta - I love the symbol of the quill, it's a great thing to live by! The Fuzzie bear is just SO cute! I also really like that you have a flag, that's a really great idea.
Chi Omega - I know so many women that are Chi O's and they are just amazing ladies! You have a very strong national which is very admirable. I always see owls as very wise, so you must be too, of course!

And who doesn't like the Make A Wish Foundation?
Delta Delta Delta - like someone else said I always think of that SNL skit! I absolutely love all of your symbols, the badge is absolutely beautiful! I know a few girls that are tridelts and they are just the most adorable girls. Children's philanthropies are important to me(obviously!) so Children's Cancer...I just can't say enough about that!
Delta Gamma - The anchor is a beautiful symbol! I just love nautical things. Helping the blind is something that I think is just too often overlooked, and it's great that you guys have that as your philanthropy!
Delta Phi Epsilon - It's great that you support those who have suffered through Anorexia. And the unicorn is an interesting mascot, I like it!
Delta Zeta - Lily Pulitzer

I just love pink and green! You guys also have a great philanthropy. I think the turtle symbol is just so cute too! My best friend from home is a DZ, so I've met many of her sisters and they're all fabulous!
Gamma Phi Beta - I like that your crest looks hand-drawn, it's beautiful. I like that your motto is "Founded Upon A Rock" - sounds like a strong sisterhood!
Kappa Alpha Theta - Laura Bush was a Theta and she's just so lovely. Every Theta I've ever met has just been amazing, and great company. I could spend HOURS talking to them!
Kappa Delta - well now I'm biased aren't I? :P I love everything my sorority's given me, so thank you to all my sisters out there! I love philanthropy, so I love that we have 4 of them!
Kappa Kappa Gamma - My aunt was a Kappa and she is a very inspiring and powerful woman. You guys are such a strong national so keep up the good work! The fleur-de-lis is very beautiful too.
Phi Mu - Pink! I love all of my Phi Mu friends and they absolutely adore Phi Mu! I really like the creed too, it's long but very significant.
Phi Sigma Sigma - I don't know a lot about Phi Sig so I had to do some research. It seems as though your vision and mission are ones that will be flexible into the future. Your founders must have been foward thinking!
Pi Beta Phi - I like the arrow, it's such a nice symbol. I like that there are 12 links on the badge for each of the founders - very touching. I like the Angel mascot too.
Sigma Delta Tau - I like the Torch symbol! And Prevent Child Abuse America is a good choice

I like that you were founded as a Jewish sorority and have become very strong, that's awesome!
Sigma Kappa - Alzheimer's is a great philanthropy and needs a lot of support, so good for you! A girl from the TV show Boy Meets World was a Sigma Kappa!
Sigma Sigma Sigma - I met a woman just last month who was a Sigma. One of the most genuine people! I like that the sailboat represents "progressing towards its destination."
Theta Phi Alpha - This is another sorority that I enjoyed learning about. I think it's interesting that you have badges for different stages of membership. And penguins are just so cute!
Zeta Tau Alpha - Stand Up Stand Out! Absolutely great girls, I think they truly support being a strong woman and not lowering your standards for others. I have a lot of respect for ZTA!
Well that's all I can think of for now!
