Mike Higashi, et. al., (& CCing admin list, as there's no reason not to)
You'd earlier mentioned bit about BALUG and publicity, etc. Although it's not exactly highly current, we *do* have a wiki page that covers that relatively well. Sort of a "how to", and what to cover (and not cover), and how, etc. We certainly don't cover *nearly* all that we could. I did also add to that wiki page your suggestion about meetup.com (I forgot the other site you mentioned, so didn't manage to add that other one). Anyway, wiki page is here: https://secure.balug.org/wiki/doku.php?id=balug:event_communications
Certainly, at least within reason, pretty much anyone can update/improve that page and/or volunteer to assist with publicity and event communications/announcements.
And for those that occasionally wonder exactly who the balug-speaker-coordinators@balug.org alias gets forwarded to, one can peek towards the bottom of: http://www.wiki.balug.org/wiki/doku.php?id=balug:balug_speaker_coordination (Yep, I even peek there rather regularly myself when I'm trying to remember exactly who is/isn't on that alias - not the authoritative reference, but I do accurately maintain it).
