[whatwg] Further working mode changes

[Anne van Kesteren]

Last week we made some further refinements to the way the WHATWG
operates and are pleased that as a result Microsoft now feels
comfortable to participate:

Let me also take this moment to remind everyone that most changes to
WHATWG standards are discussed exclusively on their GitHub
repositories (linked from the top of each standard). We also created
https://github.com/whatwg/meta to discuss things that don't really fit
anywhere else. If you want to partake in ongoing changes, either by
giving feedback or proposing your own in the form of a pull request,
GitHub is the place to be.

There are no plans to discontinue this mailing list; it'll continue to
mainly be used for announcements such as this one.
