I have closed these very old posts and polls to insure they don't get voted on any more. I didn't see any but George's name posted there, so I don't know how Dale was sent a message.
George has reported several times receiving old Forum Thread notices. We have no explanation. This is a Forum script, the most used in the world to our knowledge, and like any web tool, it has its querks.
Also... it may be that of the 20+ computers between MTU.com and George, one captured an email sent to George in the past, maybe during a virus infestation, and just released it to go on its merry way.
It is amazing to me that the Internet works as well as it does. After all, the computers are in control.
