The primary communication channel for PlasmaPy is our Matrix chat room. There is also a `Gitter bridge`_ to this chat room.
PlasmaPy's GitHub Discussions page is a great place to suggest ideas, bring up discussion topics, and ask questions in threaded public discussions.
We also have a low traffic mailing list for occasional announcements and infrequent discussions.
We have a suggestion box if you would like to (optionally anonymously) suggest a feature/topic for consideration. These will be reposted as GitHub issues, as appropriate, for further discussion.
Please check `PlasmaPy meetings`_ for regularly scheduled meetings and special events. The regularly scheduled meetings include a community meeting to discuss code development, a project meeting to discuss broader aspects of the PlasmaPy project like education and outreach to the broader plasma community, and meetings of PlasmaPy working groups. The special events include `Plasma Hack Week`_.
