So, you have found your way to the CodeReview.SE main chat room, The 2nd Monitor, perhaps for one of these reasons:

• You were invited or "pinged" by a site moderator or other user to discuss a post on the main CodeReview.SE site;
• You visited CodeReview.SE for the 1st or Nth time, and noticed the chat link under the Stack Exchange banner;
• You come from another Stack Exchange site and wanted to see what others were talking about on the network;

Whatever the reason, we are glad you are here! You may have some questions, and this post is meant to help guide you so that you have the most positive experience possible while visiting CodeReview.SE and The 2nd Monitor room.

• How do I ask questions or get help with a post on the site using chat? What topics are appropriate for chat?
• Who moderates the chat?
• What if I seek further code advice or clarification related to an existing post?
• What if I have some time to spare and would just like to rub elbows with fellow coding enthusiasts? Is some idle/fun chat allowed?
• How can The 2nd Monitor help me be a better Stack Exchange contributor, and how can it help keep me posted on what's happening on CodeReview.SE?
• Who or what else is in the 2nd monitor?
• How or where can I learn about the memes/inside jokes of The 2nd Monitor and Code Review?

This and more should be addressed by CodeReview.SE regular contributors in this thread. We hope you enjoy your time learning here with all of us!
