I have a short story that includes a chat session dialogue between two characters, and I am wondering if there is a particular way in which these are formatted according to some accepted guidelines? Write now I'm just starting with a single tab, the user ID followed by a colon, and then the text. Each user's reply is on a new line. However, in a real chat session everything is justified left -- should I add this block indentation, or just do a single tab before each user's reply like I am now? Thanks!
