Howdy 3.2 contributors: The new credits page in 3.2 (#17384) now pulls your name from your WP.org profile. So if you want your full name to show up, go update it.
Mine is here. When you’re logged in, the Edit link on your own profile and the subsequent name field are both rather obvious.
Potential contributors: This enough incentive to contribute to 3.2? 🙂 Go grab the beta.
(Fine print: Server cache updates every 12 hours. Core cache updates once a week, so you’ll need to flush the transient to see it on your own install.)
