@yangshun and I thought that this markdown-js library is not very good at parsing everything, so I will switch to a different one.

Library changed now. I am using marked for markdown parsing and highlight.js for code block highlighting. It looks pretty good on the game submission page. But, the game details page's CSS needs to be modified a little to preview the rendered html properly.

we should make sure the punctuation is not hanging (try class .prose), so the bullets appear within the textarea.
