Thank you everyone for the responses.

I've started the Community Group creation process.  Please show your
support at

     https://www.w3.org/community/groups/proposed/

The next step is to wait for 5 people to support the creation of the CG,
then W3C will create the infrastructure and we can begin.

Once the creation process has happens, there are some suggestions from W3C:

W3C page: "How do we get started in a new Community or Business Group?"
https://www.w3.org/community/about/faq/#how-do-we-get-started-in-a-new-group

W3C page "Good practice for running a group":
