Hi Greg, sorry for my terrible english, consider my small donation just as a little symbol cause i really wanted to thank you some how  for what you’re doing. I’m not joking when i say that the knowledge and the information that you’ve decided to  share in such as generous way really changed my life not only as a player but also as a person… Please continue in doing what you’re doing: maybe you don’t even imagine the incredible importance of your job but i’m sure in the future you’ll be considered one of the great innovators of the brass playing like Arnold Jacobs. thanks a lot again!  Michele Bernabei ITALY
