Formatting question

Greetings, all... $ I know there have been some people that have already voiced their opinions on the farmatting capability (or lack thereof), but I have noticed that some people have been able to do SOME formatting in their posts. $ For example, I have prepared this post in three paragraphs. I have separated each paragraph with a dollar sign to show you all where I had intended the paragraphs to be split. But as you can see, the formatting is removed, and my post is shown as a single paragraph. I've seen, however, posts with, at minimum, paragraph formatting. HOW???????
