How to Run a Successful Less Wrong Meetup is a guide that I've been working on, based on lukeprog's instructions, for the last week and a half. As it says in the beginning:

This document is written for anyone who wants to organize a Less Wrong meetup. We expect that this document will help you regardless of whether you want to start a new group or improve an existing one. We have tried to write each section so that it applies in either case.

Here's the table of contents:

• Why organize a meetup?
• How to build your team of heroes
  • The organizer
  • The welcomer
  • The learning coach
  • The content provider
  • The visionary
  • The networker
• How to announce and organize your meetups
  • Choosing a venue
  • Making the announcement
  • The first meetup
• Long-term meetup group maintenance
  • Retain members by being a social group
  • Conflicts within the group
    • Learn to recognize status conflicts

This is a draft version, so feedback would be most welcome, particularly on things like:

• Is this useful?
• Is there something that should be covered isn't covered at all yet?
• Do you have new games & exercises to suggest?
• Do you have any other content to suggest to any other section?
• Do you disagree with some of the advice given?
• Do you disagree on way something has been worded?
• Etc.

The link above will take you to a Google Docs copy of the document, with the ability to add comments to the draft. Feel free to comment on the guide either as traditional LW comments or by attaching comments to the document itself: both are fine.

EDIT: Here's the most recent version, though without the commenting ability.
