This plugin hopes to make linking to Twitter profiles easier in WordPress posts and pages.
It’s the result of typing Twitter usernames far too often in my blog posts and having to go back and link to them later, typing out http://www.twitter.com/username.
The plugin uses a basic shortcode:
[twitter]
to wrap around Twitter user names.
The plugin will then output the username with a link to their profile, displaying the standard @username format.
In addition, the links can be styled via your sites CSS, using the .twitshort selector.
<h3>Usage</h3>
<ol>
<li>Once it’s installed a quicktag/button labled “twitter” will display in your post/page edit toolbar. Clicking the link will insert the [twitter] and [/twitter] shortcode into your post/page. Simply insert the Twitter user’s name between the two short codes and the plugin will take care of the rest.</li>
<li>You can also insert the shortcode manually around the Twitter username you wish to link to. </li>
</ol>
Example: [twitter]jdblundell[/twitter]

Admin username changer

This plugin does not sufficiently check access permissions, nor does it validate the untrusted user input in any way.
In addition, this plugin can easily cause name conflicts with WordPress core code and other plugins, as it uses too generic names for classes and functions.
