All fields are optional. If you want me to respond to your message, put yes for e-mail responce, if you do not want me to e-mail you put no. I will not send you a pile of spam, sell your address, etc. (I don't see why I would want to anyway.) This is where you tell me what a bonehead statment I made, or tell me how I really need to explain myself better. Or Just want to comment or want to whatever. I will get a responce to you within a few days, if not 24 hours.
