We didn’t want to announce Wikifunctions before you can edit it (what’s a wiki if you can’t edit it?).

It is currently in locked-down testing. We have been slowly configuring and testing the wiki, the first new multilingual project in over 12 years! It is more complicated than a normal new wiki, in many ways.

We are expecting to open it to broader editing in the next few days - on or after August 1. We are planning an announcement at that time.

There are details of the deployment plan in our last newsletter: https://meta.wikimedia.org/wiki/Special:MyLanguage/Abstract_...

And a broad overview of the project at https://meta.wikimedia.org/wiki/Abstract_Wikipedia/Overview

(And many more examples of functions at our older Beta-deployment location (also currently locked down) at https://wikifunctions.beta.wmflabs.org/wiki/Wikifunctions:Ma... )

I hope that context helps! [Disclaimer: I'm not a developer, but work with the team]
