I've never heard such things about DZ nor never seen anyone haranguing you for it.
The poster who PM'd you is either ridiculously inactive on GC or using a sockpuppet. Quite brave of her to hide behind another name for such an "old poster who never posts" anymore with her *12 posts*

I'm so glad she's taking the "fall" and being "nice" with her diatribe. She also went back and delted her posts, she's down to 3 now and edited a 2005 post in March of 07.
She sounds like one of those people who think being in the "top three" at an SEC school is the only way to be Greek. And quite Classy of her to write you a long post about it.
Also, feel free to brag about your daughter as much as you would like. Bragging about one chapter on campus does not imply the rest of them suck. We all know you're a dad of a DZ, we expect to hear about DZ from you.
