I hope someone in Minneapolis sees this and gets in contact with you. Having worked there(NWA), am now retire, seems someone on the other end had a listening problem. The internet has come into big play since I worked there. Any problem with our site would most certainly be NWA's responsibility. If you could write this in a letter, you may get a better responce. Not sure if this is the right Department(everything changes)
