I am participating in a group discussing Wikimedia movement communications which I think you may be interested in joining.
The Wikimedia movement communications group is an opportunity for members of the Wikimedia community to discuss topics related to movement communications. Topics can be brought up by any members of the group, including staff from the Wikimedia Foundation Communications department. Conversations in the group may range from brainstorming communications opportunities to advance the movement to chatting about a problem faced by a specific community to coordinating communications efforts on major events.
The group is open to anyone in the Wikimedia community working on communications for Wikimedia activities or communities.
