I should add that when a manufacturer posts, and it's someone like Ralph of Atmosphere it doesn't bother me at all... his posts are often technical in nature and it's clear to me that he is doing it with the best of intentions. Plus he is informative and maybe I'll learn a little something by reading his post. Sure there are others , but he comes to mind because he is active here. As long as a manufacture does not use the forum as part of their marketing strategy , it's ok with me. In fact it shows me that they care about their products, customers, and reputation.
