Forum Post Authoring Question

I've written like six posts on here, so I apologize in advance if this is a dumb question. When I am writing a post and try to insert a blank line between paragraphs, it doesn't show up on the final post. This just happened to me in the Gaming forum five minutes ago. It's not like the world ends if I can't insert blank lines. I just wanted to try to make my posts look nicer, instead of one giant paragraph. Am I doing something wrong?
