<h2>GFM mode</h2>
<form><textarea id="code" name="code">
GitHub Flavored Markdown
========================
Everything from markdown plus GFM features:
## URL autolinking
Underscores_are_allowed_between_words.
## Strikethrough text
GFM adds syntax to strikethrough text, which is missing from standard Markdown.
~~Mistaken text.~~
~~**works with other formatting**~~
~~spans across
lines~~
## Fenced code blocks (and syntax highlighting)
```javascript
for (var i = 0; i &lt; items.length; i++) {
console.log(items[i], i); // log them
}
```
## Task Lists
- [ ] Incomplete task list item
- [x] **Completed** task list item
## A bit of GitHub spice
See http://github.github.com/github-flavored-markdown/.
