I've seen links to chat (so as not to have a conversation in the comments).
How do I create one? I've searched the meta here and unfortunately unable to find the right one.
Several ways.
[chat] expands to http://chat.stackexchange.com/rooms/38/ask-different-chat and is named Ask Different Chat which when called from the main site goes to the site chat room list (but only on the main site).
You can always copy the direct room links and embed a link shorthand using [name](URL) inline syntax as well as the [markdown method][1]
