probably want to hold comments for approval before they appear on your site (use the ‘hold comments for moderation’ option of the Discussion Settings screen to do this). Also, plug-ins can be a great help in reducing spam, and two that are highly recommended are Akismet and Growmap Anti Spambot. See the heading “Installing a Plug-In: It’s not Rocket Science” under Chapter 3, and at the plug-ins screen, search on either of these names to find and install these plug-ins.

Adding Users and Controlling User Permissions
    One of the things WordPress does automatically for you, during its installation process, is to assign a new user of the system. If you haven't changed any user settings, this lone user is the only person who can log i nto your WordPress installation. When you enter your user name and password at the WordPress login screen, you are logging in as a user. WordPress lets you have more than one user; fact is, you could have hundreds or thousands, and each could have different permissions to perform certain actions while at your WordPress site. By default, the one user added to the system at the time of installation has Administrator rights. A person with Administrator rights has permission to do virtually anything that can be done within WordPress-- add or delete other users, add, edit, and delete pages or posts, manage themes, install plug-ins-- you name it. And every WordPress user has a user profile. Go to your Dashboard, choose Users > All Users , and click on your username, and you will see your profile. An example of a profile screen is shown here .

    Most of these fields may be blank, but you can fill them in as desired. (By the way, this is also where you can change your login password if desired; just scroll down the Profile screen, and enter a new password (twice) in the boxes beside "New Password."
    If you are the only person working with (as opposed to simply viewing) your site, chances are you have no need for additional users. But if others will perform actions on your site, you will want to make them users, and give them their own login credentials. (This way, in a multiple-user environment, you can tell who has done a particular task or edited a specific post or page, because WordPress records the name of the user who last edited a post or a page.)
    At the Dashboard, choose Users > Add New to add a new user to your site. (If the 'Anyone can register' option is turned on under the Membership area of Settings > General in the Dashboard, visitors of your site are able to register themselves, by going to this site address:
    hrrp://www.your_site_name.com/register.php
    where ''www.your_site_name.com" is the name for your site. Whether you allow self-registration or not, you can always register new users at the Add New User screen, shown here.
    .
    The screen contains these fields:
    Username (required) - Enter the username of the new user here. (The entry is also used as the Login name for the new user.
    E-mail (required) - Enter a valid e-mail address of the new user here. Note that the e-mail address must be unique for each user; also, if a post or page is written by this user, then whenever a comment is made regarding that post or page, a notification e-mail will be sent to this e-mail address.
    First Name, Last Name, and Website- These fields are fairly self-explanatory, and all are optional.
    Password (twice) - Enter a password for the new user twice here, once in each text box. (For adequate security, it's recommended that passwords be at least 7 characters in length, contain at least one numeral, and have a mix of upper and lower-case letters.)
    Send Password? - If you turn on this check box, the password will be sent to the new user via email.
    Role - Choose a desired role for this User from the drop-down box. (Your choices here are Administrator, Editor, Author, Contributor, and Subscriber, and you can change the default role for all new users by going to the Settings > General screen within
