Subject: WhatsUp from: #{start_date} until: #{end_date}

Hi! We're sending this automatic email twice a month, to give the community an opportunity to easily know what's happening and to coordinate efforts.  Just answer informally, and feel free to spawn discussions thereafter!

### Here's what I've been up to since the last WhatsUp:

- $HEROIC_ACHIEVEMENTS_OR_DISMAL_FAILURES_OR_SIMPLE_BORING_NECESSARY_TASKS

### What's next, until #{end_date} (*):

- $NEXT_STEPS_TOWARDS_WORLD_DOMINATION

(*) we'll be expecting results by then ;)
