A few days in the making, you can now associate any review you write with any teams you’re a member of. This is a central idea of lib.reviews and it will take a while to get it right. Think of teams like sub-reddits or Facebook groups, places where people who care about the same thing can organize their work.
Next up, to make this more useful, you’ll be able to get Atom feeds as well and see the latest reviews on a team’s page.
