It’s been a few weeks since we’ve posted an update, @mikeschinkel has been working hard on some new commits to give us some shortcuts for option arrays and things have stabilized there finally. We’re now focused on documenting field type development so we can get some contributors in there fleshing out the remaining field types.
We are also moving our “Office Hours” time and place, to Mondays @ 1800 UTC , but instead of IRC where people can’t sync up and collaborate, we’re moving it to our public Gitter room. Some other WP projects are using it and we’ve found it incredibly helpful to keep up with GitHub activity along with chat that can happen at all times of the day and it sticks around for you to read anytime you want to.
Our Gitter chat can be found here: https://gitter.im/wordpress-metadata/metadata-ui-api
Anyone can see the chat messages, and if you want to participate it’s just a GitHub login away. They have iOS / Mac apps too, so that’s helpful to some people as well.
If you’re interested in contributing, or if you want to check out what we’ve got and need some insight, just ping us — anytime — in Gitter
