This plugin is DEAD until further development. 
Don’t use it as this can lead your WordPress instalation into problems.
With this plugin you can change wp-admin and wp-login.php to any of your choice. 
You can have <code>http://example.org/login</code> instead of <code>http://example.org/wp-login.php</code> or <code>http://example.org/admin/</code> instead of <code>http://example.org/wp-admin/</code>
You just need to enter into <code>options-permalink.php</code>page and set the variables. 
After the setup wp-login.php and wp-admin path are not anymore available and you should use the newest onews you set.
This works with Multisite Networks. You can set a default value in Options page of Multisite settings section.

A WordPress plugin which gives the ability to zoom in/out on various text elements (think user readability enhancement). After a user edits their zoom level the plugin sets a cookie so that it will remember their setting and use it.
<h3>Installation (not necessarily in order)</h3>
Step One: Simply apply the CSS class “larger” to whatever text element that should have the ability to be resized (NOTE: this is best implemented on a responsive design, for obvious reasons).
Step Two: Add in the “buttons” which will trigger the font re-size. These buttons should have the classes of…
Zoom In Button = “zoomIn” 
Zoom Out Button = “zoomOut”
Step Three: Install the WP plugin and activate it.
Step Four: Wow your users with text that is easily read, no matter how bad their eyesight! 😉
