Notes on running a "public" slack

public-slack.md

My recommended settings for setting up a slack that you plan to allow public access to. Methods for adding public users include third-party utilities like slackin (https://github.com/emedvedev/slackin-extended) which enable active user badges, or simpler methods such as using the Share Invite Link from slack itself.

SUPER IMPORTANT

If you only do two things, make it these two: Make sure to disable all app integrations. There's a bunch that aren't secure for public slacks. Either deny all, or require review by an admin: https://YOURSLACK.slack.com/apps/manage/permissions Second, disable email in the profile view: https://binaryninja.slack.com/admin/settings#display_email_addresses

The reset are optional settings that may or may not be required depending on the slack:
