IF anyone is interested Michael Smith has a website on Azo paper and is one of the only real true crusaders of keeping it on the market. I buy from him because if it wasn't for him and paula we wouldn't have azo anymore. also he has a forum on azo and developers so give it a try and learn about azo and the different deveopers his azo followers use. By the way when michael and paula are in town they answer questions on the forum all the time.regards
