The one I really like doesn't specifically focus on Greek life, but it has a lot of really great posts like "Is sorority life for me?" and "Should I live in the sorority house?" and ideas for crafting and food. It also has other really great articles, like the most recent one "What do I do? My friend has an eating disorder". The website is
www.collegelifestyles.org
They have a lot of unpaid interns too who are members of all different sororities, so feel free to check it out.
