<p>This plugin changes the WordPress’s native formatting rules to keep the numbers of the line breaks you wrote.<br />
It adds <br /> tags as many as line breaks in posts, comments, or both, even if the line was vacant.<br />
You can change the settings below in the admin panel. For example: you can choose to add <p> tags for wrapping the paragraphs or not.</p>
<h4>Settings</h4>
<p>You can choose settings below.</p>
<ol>
<li>Choose the target area: in posts, comments, or both(default).</li>
<li>Choose the breaking tag format: <br />(default) or <br>.</li>
<li>Choose the tag which the paragraphs will be wrapped with: <p> tag(default) or none.</li>
<li>Shortcodes that you want to exclude from <p> tag wrapping.<br />
This doesn’t work if you choose “none” in option #3.<br />
Default is only “caption” but you can set multiple shortcodes separating “|”. Ex. “caption|map”</li>
</ol>
<h4>Attention</h4>
<p>This plugin doesn’t work with the Visual Editor, so far.</p>
<h4>For Japanese users</h4>

Vacant Line BReaker

Wordpress ignores multiple line breaks normaly. This plugin breaks lines as may as you want.

<p>Markdown for WordPress and bbPress (Markdown-WPBB) is based on the famed PHP Markdown Extra by <a href="http://www.michelf.com/projects/php-markdown/" rel="nofollow ugc">Michel Fortin</a>, in turn based on the original Perl version by <a href="http://www.daringfireball.net/" rel="nofollow ugc">John Gruber</a>. All I did was make the same package work with bbPress too. ^^</p>
