How do I disable join/leave messages in Slack?

Not as it is at the moment, no, unfortunately.One thing you can do, is to mute the channel.If that is not an option, then you're out of luck. The last thing I heard about this was in august 2015, where this tweet was made by Slack on Twitter:@SlackHQ: can we hide join/leave messages through global or channel  settings?@willimac not at the moment but we're glad to send your  request over to our team!I myself have been using this userstyle as I'm only using Slack for WordPress: https://userstyles.org/styles/106647/wordpress-slack-hide-join-leave. I don't know if this is something you will be able to modify or user for other use cases.WordPress also links to this at their official page about Slack, so I'm guessing that there isn't an official solution out there yet :/
