Here's what I propose.
I will start a new pinned topic on the Goverance category called Transition Status.
It will have much of what was described at How can we contribute developing new features? - #5 by yanokwa but with less focus on Aggregate and will be reviewed by the project leadership before it goes live.
Project leadership can publish updates on the transition on that thread and the community can subscribe to it to get updates (including summary of meetings). We'll also try to summarize these updates when we do Announcements.
I will also write a blog post on the ODK website that links to that page and tweet out that link. I will also update the Participate page on the ODK website to have a pointer to the thread.
If that sounds reasonable, please like this post. If it's not reasonable, please suggest some alternatives!
