Wanted to put my own shout out to my own Yii powered website! 
[indent]www.wirecar.org[/indent]
I am using Yii along with MySQL to provide a database service to non-profits and non-governmental organizations. The site helps organizations manage and report on the services they provide to their clients. This helps non-profits satisfy donor reporting requirements while saving time and hopefully translating into more donations so an organization can help more people in need.
Jay.
PS: It’s a simple site, designed to work even with very low bandwidth.
