I am glad to report that, per previous conversations in the ambassadors'
group, a Phabricator workboard to coordinate work for the group has been
created. You will find details, and requests for your input, in the update
I published at Meta . We're approaching this slowly so that there's
plenty of time for people to get a proper onboarding and to get to know
Additionally, you can chat about this and other topics with me in person if
you're attending the Wikimedia Conference this week in Berlin . I will
also be around during Learning Days. Please don't hesitate to come talk to
me! If you can't find me, try Telegram or Twitter :) 
There will be other occasions to discuss these topics soon, FWIW.
Looking forward to hearing from you soon,
Manager, Community Liaisons
