We've been working on revamping the Meta pages describing our global branches. https://meta.wikimedia.org/wiki/The_Wikipedia_Library/Global is the new global hub, linking to individual pages for each language branch currently operating and outlining what each branch has. Each language page also has a space to discuss and coordinate the branch. Feel free to edit your branch's page, particularly to add any projects you're working on that I might have missed. Take some time to explore what other branches are doing. I'd love to hear any comments you might have about this setup for global coordination.
I've also created a global "checklist" of sorts: https://meta.wikimedia.org/wiki/The_Wikipedia_Library/Global_checklist . This checklist is meant to guide the development of new pages globally, by outlining some best practices for basic TWL page development. The checklist is a draft, and any and all feedback is welcome at its talk page.
