Why, when I compose a post, can I do this:

[paragraph]

[another paragraph]

Now, when I type that in the WYSIWYG editor, there is an empty line between the above "paragraphs". But when "post" or even "preview" is clicked, suddenly the empty line is gone and what is left is an ugly wall of text. Therefore What You See Is NOT actually What You Get.

[there should be another empty line here but it's not going to work]

What's the issue? I see other posters with line spaces in their posts, am I using the wrong browser? I thought it was a Firefox thing but it seems to persist even in Chrome.
