The email is form generated when a moderator performs any kind of management within a forum. It allows the moderator to insert any pertiinent information concerning the maintenance that is being done. In your case, it stated that your thread in the Tips & Techniques forum was deleted. Normally, the reason that I place in the body of the email is something like, "It is against RCU community polcy to post a thread to multiple forums. The thread in the Scratch Building forum will remain." I don't have a copy of the email so I can't send it to you but it was along these lines.
