Email can reach many hobby personalities and game companies.
For the definitive list of these see the Wargame Company Email Address List , run by Skip Franklin, to whom all new or changed entries should be sent . The Address List was started by Joe Boeke. Rather than contact individuals, the best way to stay in touch with what is going on in wargaming is to join a mailing list , a group of people who all want to talk about one topic. Some wargames have their own mailing lists. It ought to tell you how to unsubscribe from the list and what address to use for postings.
