Content Formatting

I don't know if it's intentional, but forum, comment, article, etc. posts don't show up aligned like they're entered. For example, this is a new paragraph separated by a blank line. Or is it... So is this, and all of the new paragraphs aren't indented by me, but they are! I think this could use some tweaking, what does anyone else think? Or am I using the incorrect input format? Hmm hmm...
