For creating recipient lists when announcements or feedback requests need to be done to a lot of users at once, the communications team uses this tool https://technischewuensche.toolforge.org/newsletter/.
It automatically generates the list of users in the format for sending MassMessages e.g. {{target | user = usernamexyz | site = de.wikipedia.org}}

The list of users who voted for the "Reusing References" focus area as their first preference needs to be added to the tool. The section with the focus areas is down below.

Thanks!
