Some slight aesthetic modifications

Hello. This is xpwifi from DIY. I made a change to the border of your posts. It puts the border around the entire post rather than one border per paragraph. In order to use the border in the future, just put a div around the post with the "post" class in it.
Example:
<div class="post">
    <p>Hello World!</p>
</div>

I basically just pasted the border css from the paragraph tag in main.css and put it in .post.
