Just a quick note that the way to get what looks like a pre-formatted set of lines that follow each other is to put all the text in a single line, but insert <br> tags where one wants single line breaks.

So, for example, this:

> line one<br>> line two<br>> line three

is rendered:

line one<br>> line two<br>> line three

Hmmm... I see whatever processes a post *does* want to isolate separate lines, even when they were intended to be displayed one right after the other.
