Formategory allows you to customize posts based on their categories. Just define a template for a category, and all of the posts in that category will be displayed according to the template.
Use the buttons in the top-right meta box to insert placeholders for the post’s content; {{ the_content }} will be replaced by the post’s content, and {{ the_title }} will be replaced by the post’s title. Select some categories for the template, and after you save it, any posts in those categories will be instantly templated.
The “Category Templates” page in your dashboard allows you to manage your templates just like you manage your posts and pages.

A simple way to customise the login screen on your WordPress install. There are a number of advantages to using this plugin:
<ol>
<li>Using a plugin means the changes stay when you upgrade</li>
<li>It’s an easy way to add a little polish to your freelance web design jobs</li>
</ol>

Custom Login

Not too much, not to little, just right.  Allows for custom logo, font and button, and a little extra CSS if needed.  Based on the size of your logo you will need to adjust the background position and/or margins of the #login but with a few tweaks it looks great.
