Let me explain. Tried e-mailing STP and I kept getting a error message "Simple characters only." After awhile I realized that I use a break between the greeting and the body. I kept getting error message, but I was only using simple characters. Tried calling STP 888-464-7871, and receive a message "We are experiencing system problems."
Original post was about simple characters, but I couldn't delete it after I figured it out. Just thought I should explain.
