WordPress Permalinks
Permalinks, or slugs, are the links in your address window that appear once you click on a page to read it in its entirety or email a link to go directly to that post. For example, I use permalinks for all of my NY Times articles on this blog. My default WordPress permalink was the “ugly” (see tutorial link below for what I mean by this). Structure tags may be configured in a multitude of ways. However, in order to configure permalinks, you need to learn how manipulate your software. I started out by using Google to search for WordPress slug. I found this helpful tutorial entitled Using Permalinks.
You first need to look in your server for a .htaccess file. If you do not have one, open up a new document in your text editor (such as TextMate) and save it as “.htaccess”. 
Once you have this file, upload it to your server. This seems a little odd to upload a blank document, but once you follow all of the instructions, it will make more sense. Once the file is in your server, right click (or CTRL+click on a Mac) and choose the “get info” option. At the bottom of this new window, you will see “Octal:” and you will be able to change this to “666″. Press apply and close the window. Next go back to WordPress — Options — Permalinks. You will have a few choices, but at the bottom, you will have a custom preference. You may use the structure tags in the tutorial to customize the permalink to your preference. I personally choose to insert “/%postname%/”. This article should read <http://www.theblogbitme.com/wordpress_permalinks>. Now you are ready to go back to your blog and check to see if this new option is working. Please remember that you will have had to save a previous post with a post slug in order to check to see if it is indeed working. You will see the post slug option in WordPress under Write — Write Post on the right hand side of the page. Good luck!
