With this plugin you can insert icons Font Awesome inside your post. 
Simply select the desired icon and will be automatically entered in the shortcode that will allow you 
to customize the icon and select the size, color, and if the icon should be fixed.
The characteristics of the plugin are:
<ul>
<li>This includes more than 400 icons</li>
<li>No need to modify your templates to include the icons, but just select and insert them into your post</li>
<li>
The icons are divided into the following groups: 
New Icons in 4.0, Web Application Icons, Forms Control Icons, Currency Icons, Text Editor Icons, 
Icons Directional, Video palyer Icons, Brand Icons, Medical Icons
Note that the <code>readme.txt</code> of the stable tag is the one that is considered the defining one for the plugin, so 
if the <code>/trunk/readme.txt</code> file says that the stable tag is <code>4.3</code>, then it is <code>/tags/4.3/readme.txt</code> that’ll be used 
for displaying information about the plugin. In this situation, the only thing considered from the trunk <code>readme.txt</code> 
is the stable tag pointer. Thus, if you develop in trunk, you can update the trunk <code>readme.txt</code> to reflect changes in 
your in-development version, without having that information incorrectly disclosed about the current stable version 
that lacks those changes — as long as the trunk’s <code>readme.txt</code> points to the correct stable tag.
If no stable tag is provided, it is assumed that trunk is stable, but you should specify “trunk” if that’s where 
you put the stable version, in order to eliminate any doubt.
</li>
</ul>
<h3>Attributes</h3>
After selecting the icon will be entered one shotscode in your post, 
which you can customize as follows:
Example: [fontawesome icon=”fa fa-anchor” size=”lg or 2x or 3x or 4x or 5x” iconcolor=”” fixed=”yes or no” ]
size
<ul>
<li>lg or 2x or 3x or 4x or 5x: select one of these options to set the size of the icon. 
For example size=”lg” is the smallest icon size=”5x” is the largest. 
Starting lg option, any other option increases the size of 33%</li>
</ul>
iconcolor
<ul>
<li>iconcolor: For example iconcolor=”#CCCCCC” for your icon grey.</li>
</ul>
fixed 
* fixed: For example fixed=”yes” to set icons at a fixed width.
