In the future, when you join a public forum please take the time to acquaint yourself with the rules and operation of the board. That would include how to properly post questions, where to post them, and what behavior is considered acceptable.

I would suggest you start in the Site Orientation forum.

This is a public forum run by volunteers who have jobs, children, homes, spouses, businesses, and all their own problems. If you have a problem so important that you would attempt to circumvent the restrictions of the board to the point of being annoying then I suggest you find and pay somebody who does this for a living and is willing to help you immediately. Otherwise, it is rude and unacceptable behavior to use my personal comments section as your messaging board. I sure hope you didn't do that to anybody else, and if you did I suggest you attempt to delete those comments or apologize to those users or you may not get help from anybody.

I'm sure somebody around here will be willing to help you, but I will kindly pass…
