First of all, being one of the people that voted for this worker, congratulations!
Some suggestions in getting started (which to be fair I believe you're probably already acting on)
a) Create an internal comms channel (be it slack, telegram group, whatever) between the UI , Core, BBF teams as well as commitee members) so that the BBF is notified of any events/changes/bugs/releases/etc. in order to make appropriate and timely announcements.
b) Figure out what the official public-facing communications channels will be for Bitshares. One of the main ones should be an official and VERIFIED twitter account imho.
c) At least one person from a different time-zone should be part of the team handling those channels in order to provide updates and notifications for events outside BBFs "normal" working hours.
Although such communications and notifications are "mundane" and not the same business-wise as say representing Bitshares at a conference, they will do wonders for the "public image" of the Bitshares ecosystem.
Hope the team does well!
