Returns the facility, its opening date (opensOn; crewsOpen false before it), the opt-in Link & Dink crews there, and the start page's routing: the five starting points a person can pick from (new, learning, regular, competing, organizing), which crew each leads to and why, and the organizer path. Use it to answer 'how do I join / where do I start at Game On' and point the person at start.url, or at the recommended crew's /groups/<slug> page. Starting points are routing choices, never ratings.
