The google group mailing list of LessWrong Brussels (and related loose list of email addresses from people who expressed interest) is more of a chore than a tool these days. I'm retiring it and making the
Meetup.com page our primary hub. I'm hoping it'll be a lower barrier to casual conversations, but at the very least it does meetup announcements automatically. If you want to be kept up to date with LW Brussels, please go and make an account there.
