a couple of things...
In the future I would just ask in the original e-mail if it's ok to post, that way you don't have to wait, and have board members hound you about if you are going to post or not.
Brian doesn't ask permission to share your e-mails with his crew, so I wouldn't worry to much about getting permission...he knows who is on this board, and he most likely assumes any response is going to be posted.
