After installing Drupal, you're presented with some initial configuration tasks.

First User

This first user account you're asked to create is like root . I set:

Username

webmaster

E-mail

webmaster@domain

Because this account has infinite privilages, and little accountability because it is not associated with a specific person, its use should be avoided.

Our User

1. Create a "regular" user account for yourself (as suggested by the Drupal installation's initial homepage), and assign it appropriate roles (privilages) (so you can still get work done)
2. Logout as webmaster and login with your own user account

Clean URLs

I think Clean URLs are so important they should be our first real customization.

1. Enable Apache's Rewrite module: a2enmod rewrite ; invoke-rc.d apache2 force-reload
2. Enable Drupal's Clean URLs: Administer, Site configuration, Clean URLs
