After the workshop: Then what? 

The vast majority of the work to be done will happen after St. Louis. 

Part of the goal of the workshop is to establish exactly how we want to direct the core working group for the next six months and what milestones are important to achieve. The document at  TGE Initiative - Post-workshop Goals and Plan gives some general ideas, but expect that plan to evolve radically based on what we come up with together.
