At the college where I teach, I just found out they offer free legal advice to faculty / staff / students. Not sure if this service is available in the summer, but plan to look into it today. And good idea on the letter, EW. We are drafting one. I also like Jad's idea for contacting the health dept. I think we will put this all in the letter as well as contacting the local health dept. We also have a local news station that will look into matters like this. I may threaten him with that one, too.
Funny thing--my allergies have already improved since leaving the place. Also, the a$$hat had the audacity to suggest I am asthmatic due to my cat and "should get rid of her". Ummmm yeah right. Had the cat long before the mold and never had issues before with her exacerbating my allergies. People like this guy just make my blood boil.
