Welcome aboard! I haven't checked out your shop yet but will. Self promotion is a touchy one. Check the rules on the board here is all I can say. I wouldn't stay away from forums because of it though. I'm also on a bunch of different woodworking forums and the owners of a couple very major brands are part of them too. They don't advertise on the boards but they will answer questions directed at thier products and there have also been instances where forum members have had problems with their products and the response is "I wish you had come to me first." They're very good about clearing up any issues or misunderstandings about the items they sell. Overall they're very valuable members of those communities.
