y4d

1) You can decorate your messages.
* `*bold*`
* `/italic/`
* `_under line_`
* `-through line-`
* \`small code\`
2) You can use the notation like GitHub to highlight source code.
```js
var hello = "world";
```
3) For non y4d users, y4d converts spaces to multibyte-spaces before submit messages.
