J_R you have to go to the notification email that wa sent to you and in there there is an option to unsubscribe from the thread. Once you follow the link it will bring you to the board and give you a message saying that you successfully unsubscribed from that thread.
Please cutback on starting new threads and try to post messages as a reply to existing threads.
If you want to cut and paste from your word processor do not do it directly. First paste it into notepad or other basic ascii editor so that the formatting codes are removed, then cut again. This will give you clean posts.
