She has a fantastically useful blog up with relevant information:

Yoga City NYC has hired reporters to follow the matter, and post daily about the situation, meaning up-to-date all-round information, interviews and so forth: http://yogacitynyc.com/yoga_week.php#39

The law itself: http://www.highered.nysed.gov/bpss/revisedlaw.htm

You should write, as some of us already have, to Mayor Michael Bloomberg (this concerns NYC residents–yoga teachers and those who receive the benefit of Yoga–, Senator Eric Schneiderman and Governor David Patterson. The more letters they receive, the better. Emails and addresses at “Contact” on their websites, if you don’t already have them. Other major NY studios have lawyers addressing the issue and are in contact with various State officials. We hope to co-ordinate our efforts, even though each center has a different mission and may be affected differently by the law.

Take the name “school” out your name if it’s there. There are laws about that too!

Namaste!
