The Go Center membership and game system has been significantly overhauled, and an automated ranking system has been added. Changes you’ll notice are:

• There are pages for each member, showing their games and rank history. Look for the little ≡ symbol next to each member’s name. It links to the member’s history page.
• Ranks are automatically tracked and updated based on game results. They are computed using our new ranking system.
• Ranks are recorded in the game records and appear in SGF files.
• The old “membership” board in-world has been replaced with a simpler “ranking” board. No longer any need to “join” the center – just estimate your rank and play games!
