After an unexpectedly long hiatus, editing of MDN has officially returned. Starting a few hours ago, clicking the “Edit” button on MDN automatically reroutes you to the beta Kuma wiki site, which is located at https://developer-new.mozilla.org/. You will have to log in again using Persona (formerly known as BrowserID) when you get to the new wiki, but once there, you can edit to your heart’s content.
While you’re there, feel free to poke around, check out the scene, and file a bug or two if you have any problems. There’s a handy “Report a bug” button at the top right of every page!
For the time being, the existing site will remain the primary site for reading (which means, yes, the content is going to start growing stale). However, we hope to officially launch the new wiki in the next couple of weeks, assuming things continue to go well. My fingers are crossed, because we’re having a team meeting to talk about our successful launch and what to do next to continue to improve the site in the second week of August!
