Getting satisfied students and graduates to volunteer contact information is a problem. People value their privacy and get very upset about Spam.
Under the new US laws in regard to privacy and Email, (CAN- SPAM Act of 2003), this illegal and subject to criminal prosecution.
Unless, I have their written permission, I cannot post their contact information, no matter where they come from.
On our testimonials page, there are two people who gave permission and did volunteer their Email contact information: http://www.yoga-teacher-training.org/testimonials/
Some of our Yoga teacher graduates have listed their web sites. So, it is possible to contact them as well.
