Edit posts, pages, or custom post types by adding a “/edit” to the end of the URL. If you are not logged in, you will be prompted to log in in order to edit the item.
Send clients pretty URLs to the admin instead of a ton of query variables!
The “/edit” functionality also works on author and taxonomy archives, and if you have a page assigned as your front page of your site.

This is useful if:
<ul>
<li>You are not logged in, and want an easy shortcut to edit an item.</li>
<li>You hate the admin bar and have disabled it, but still want an easy shortcut to edit an item.</li>
<li>You have clients. Send them a pretty URL with “/edit” on the end.</li>
</ul>

Category reminder uses javascript to assert that a category has been assigned 
to a post before publishing it. If no category is assigned, then it will 
prompt the user to assign before publishing.

Category Reminder

This plugin requires users to assign a category to each post other than "Uncategorized".
