I've been reading through some of my old boxes wargames on my breaks at work. Earlier I found this in one of them:
"Should you have any difficulty interpreting the rules, please write to XXXX, phrasing your questions so that they can be answered by a single word or sentence. You must enclose a self-addressed, stamped envelope."
How's that for a reminder that a game was produced before the widespread use of the Internet? And this is one of the newer games on my shelf!
