<para>
Comments are an optional &product.longname; feature that allows your web site's audience
to provide feedback for the content they see. You can choose to:
</para>
<itemizedlist>
<listitem>
allow or disallow comments individually for any content entry
</listitem>
<listitem>
require users to be logged in to comment
</listitem>
<listitem>
display or hide comments when the associated content entry is viewed
</listitem>
<listitem>
hide comments unless they are approved, or the user is authenticated
</listitem>
<listitem>
allow voting on comments
</listitem>
<listitem>
restrict voting to once per user per content entry, if voting is allowed
</listitem>
</itemizedlist>
<para>
Authenticated users automatically have their userid associated with their comments.
Unauthenticated users need to provide a name and optionally an email address, as well as
successfully satisfy a <acronym>CAPTCHA</acronym> to prevent automated commenting. For both
types of users, if their email address is registered at
<ulink url="http://gravatar.com/">gravatar.com</ulink>, their custom
<emphasis>avatar</emphasis> graphic is displayed alongside their comment.
