ACTION-63: Slide decks for specific topics?

Slide decks for targeted needs:

Getting started (chair, setup)
Getting to success in your group (developing scope, setting expectations in charter format, motivating participants, working effectively, publishing)
Progressing to the standards track (transition)

I'd say this has largely be overtaken by events.

Closing with note that:
* The CG FAQ entries should suffice.
* The Community Council wiki https://www.w3.org/community/council/wiki/Main_Page also holds topics documentations.
