The more I utilize WordPress, the more I want to secure it. The one thing that bothers me, is the lack of being able to change the admin username. During a Google search, I ran across this, and wanted to share.
To change the default admin username, take the following steps.
Step 1: Open your database via phpmyadmin, or another MySQL browsing tool
Step 2: Locate the wp_users table and browse it.
Step 3: Edit the “admin” user.
Step 4: User user_login, change the “admin” to whatever you want.
Make sure you don’t forget it! 
I hope that helps someone out there.
