[tc][forum] documenting "forum 101"

Hi everyone,

We've discussed the idea of building a document which provides information on how to host a good forum session, tips and tricks, how to make the best out of them. It seems there's content all over the place but not aggregated in a single good spot that we can point attendees/hosts to.

context: http://eavesdrop.openstack.org/irclogs/%23openstack-tc/%23openstack-tc.2019-...

Do we have any volunteers from the TC (or even community members) that are interested in this effort?

Thanks, Mohammed
