You might want to add NPC's websites, thesororitylife.com for PNMs and
www.sororityparents.com for parents.
I also like Tammy's blog,
www.sororitygirl101.com
We also add the panhellenic websites at the universities most attended by our hometown girls. The list of helpful websites (and it includes greekchat.com) is snatched up by moms and girls alike.
