This is a matter that I cannot simply edit away. There are some people on this forum using line breaks incorrectly, and it's extremely irritating to me. kilarney and blast flame are the most recent offenders.
When writing on the Internet, you just leave two carriage returns between each paragraph. Not one. Not three. You start a new paragraph when the subject changes substantially, the point is complete, or the speaker in quotation marks changes. You do not just leave single carriage returns around willy-nilly. It's sloppy-looking, and makes your writings difficult to follow.
