ARRL has a Groups.io and Discord server for Public Information Officers and others.  We use it to share ideas and events in promoting Amateur Radio.

For links to join, send an email request to newsmedia@arrl.org

The Group and Discord were designed to provide a forum for sharing information and ideas about Amateur Radio related PR topics. Share your successes, your PR dilemmas or ask a question. The list contains a lot of PIOs, media professionals and ARRL officials who can offer helpful advice. It is important that we keep all postings on the topic of public relations. Messages that are off-topic are an inconvenience for those who are here to discuss Amateur Radio public relations.
