Here's the Astral Codex Ten worldwide meetups list, crossposted at LW's request in case people here are interested in attending. Some cities have an ACX but not an LW meetup group, or vice versa; others combine their groups. You can find the list below, in the following order:

Africa & Middle East
Asia-Pacific (including Australia)
Canada
Europe (including UK)
Latin America
United States

You can see a map of all the events on the LessWrong community page.

Within each section, it’s alphabetized first by country/state, then by city - so the first entry in Europe is Vienna, Austria. Sorry if this is confusing.

I'll provisionally be attending the meetups in Berkeley, Los Angeles, and San Diego. ACX meetups coordinator Mingyuan will provisionally be attending Paris and London. I’ll be announcing some of the biggest ones on the blog, regardless of whether or not I attend.

Extra Info For Potential Attendees

1. If you’re reading this, you’re invited. Please don’t feel like you “won’t be welcome” just because you’re new to the blog, demographically different from the average reader, or hate ACX and everything it stands for. You’ll be fine!
2. You don’t have to RSVP or contact the organizer to be able to attend (unless the event description says otherwise); RSVPs are mostly to give organizers a better sense of how many people might show up, and let them tell you if there are last-second changes. I’ve also given email addresses for all organizers in case you have a question.

Extra Info For Meetup Organizers:

2. Bring blank labels and pens for nametags.
3. Have people type their name and email address in a spreadsheet or in a Google Form (accessed via a bit.ly link or QR code), so you can start a mailing list to make organizing future meetups easier.
4. If it’s the first meetup, people are probably just going to want to talk, and if you try to organize some kind of “fun” “event” it’ll probably just be annoying.
5. It’s easier to schedule a followup meetup while you’re having the first, compared to trying to do it later on by email.
6. In case people want to get to know each other better outside the meetup, you might want to mention reciprocity.io, the rationalist friend-finder/dating site.
7. If you didn’t make a LessWrong event for your meetup, the LessWrong team d...
