Some committers are also monitoring <a href="#stack-overflow">Stack Overflow</a>. Please remember to tag your questions with the <em><a href="http://stackoverflow.com/questions/tagged/apache-flink">apache-flink</a></em> tag. Bugs and feature requests can either be discussed on the <em>dev mailing list</em> or on <a href="#issue-tracker">Jira</a>.

<p>If you send us an email with a code snippet, make sure that:</p>
<ol>
<li>you do not link to files in external services as such files can change, get deleted or the link might break and thus make an archived email thread useless</li>
<li>you paste text instead of screenshots of text</li>
<li>you keep formatting when pasting code in order to keep the code readable</li>
<li>there are enough import statements to avoid ambiguities</li>

<h2 id="slack">
Slack
<a class="anchor" href="#slack">#</a>
</h2>
<p>You can join the <a href="https://join.slack.com/t/apache-flink/shared_invite/zt-1t4khgllz-Fm1CnXzdBbUchBz4HzJCAg">Apache Flink community on Slack.</a>
After creating an account in Slack, don&rsquo;t forget to introduce yourself in #introductions.
Due to Slack limitations the invite link expires after 100 invites. If it is expired, please reach out to the <a href="#mailing-lists">Dev mailing list</a>.
Any existing Slack member can also invite anyone else to join.</p>
<p>There are a couple of community rules:</p>
<ul>
<li><strong>Be respectful</strong> - This is the most important rule!</li>
<li>All important decisions and conclusions <strong>must be reflected back to the mailing lists.</strong>
&ldquo;If it didn’t happen on a mailing list, it didn’t happen.&rdquo; - <a href="http://theapacheway.com/on-list/">The Apache Mottos</a></li>
<li>Use <strong>Slack threads</strong> to keep parallel conversations from overwhelming a channel.</li>
<li>Use either <a href="https://apache-flink.slack.com/archives/C03G7LJTS2G">#pyflink</a> (for all Python Flink questions) or <a href="https://apache-flink.slack.com/archives/C03G7LJTS2G">#troubleshooting</a> (for all other Flink questions).</li>
<li>Please <strong>do not direct message</strong> people for troubleshooting, Jira assigning and PR review. Doing this can result in removal from Slack.</li>
</ul>
<p><strong>Note</strong>: All messages from public channels in our Slack are <strong>permanently stored and published</strong> in the <a href="https://www.linen.dev/s/apache-flink">Apache Flink Slack archive on linen.dev</a>. The purpose of this archive is to allow search engines to find past discussions in the Flink Slack.</p>
