title: Send messages from Jenkins to multiple Slack channels
body: <p>According to the main <a href="https://github.com/jenkinsci/slack-plugin#install-instructions-for-slack" rel="noreferrer">Jenkins-Slack documentation</a> you have to configure the Jenkins app for slack and there you specify a single channel where the plugin can post. Now in my case, I need to post to multiple channels and users from a Jenkins server and it is very cumbersome to manage multiple auth tokens. Is there a way to have a single token that would work with all the channels and users? Are there other approaches? I see that the Jenkins plugin has a <em>bot</em> checkbox, but there is almost no documentation on how to make this work.</p>
