Proposing some invited experts

This is my first time participating in a W3C Working Group as a member, so
please forgive me if I'm doing this wrong!

I'd like to get us started filling out this group. In particular, I'd like
to invite the person we named as potential chair, so he can begin doing the
work of chairing. I'd also like to invite the authors and editors of our
three primary scheduled documents.

So, here are the names I'd like to get involved:

- Darius Kazemi (Applied Social Media Lab, Berkman Centre, Harvard
University). Darius has been a long-term participant in the ActivityPub
community, is an excellent communicator and leader, and is named as a
proposed chair of this group in its charter.

- James Snell (Cloudflare). James was an editor of the Activity Streams 2.0
Core and Vocabulary documents.

- Christine Lemmer-Webber (Spritely Institute). Christine was an editor of
the ActivityPub specification.

- Jessica Tallon (Spritely Institute). Jessica was also an editor of the
ActivityPub specification.

- Erin Shepherd (Qonto). Erin was the original author of ActivityPub.

- Amy Guy (various). Amy was the author of the Social Web Protocols Note
and an author of ActivityPub.

Some of these people have drifted away from AS2/AP and even the Web in
their careers, but I think it makes sense to extend invitations to them as
a courtesy.

There are a number of other people in the ActivityPub community I'd like to
bring on, but these seem like high-priority invitations.
