## HTML Comments
Comments can be configured to contain a restricted set of HTML tags
through the `html_allowed` and `html_allowed_elements` settings.
Raw HTML is hardly user friendly, but combined with a rich-text editor
of your own choosing it can allow rich comment formatting.

In order to use this feature, you need to install the
[HTMLPurifier](http://htmlpurifier.org/) library.
The easiest way to do this is through [Composer](http://getcomposer.org).

**Important**: Rendering user-provided HTML on your website always risks
exposing your users to cross-site scripting (XSS) attacks, if the HTML
isn't properly sanitized. Don't allow tags like `<script>` or arbitrary attributes.

If the email address used to comment does not have a gravatar, it is possible
to configure the default image shown. Valid values can be found at
http://gravatar.com/site/implement/images/, and at the time of writing are the
following:
* 404: do not load any image if none is associated with the email hash, instead
return an HTTP 404 (File Not Found) response.
* mm: (mystery-man) a simple, cartoon-style silhouetted outline of a person
(does not vary by email hash).
* identicon: a geometric pattern based on an email hash
* monsterid: a generated 'monster' with different colors, faces, etc
* wavatar: generated faces with differing features and backgrounds
* retro: awesome generated, 8-bit arcade-style pixelated faces
* blank: a transparent PNG image (border added to HTML below for demonstration
purposes)
To change the default image style, add the following to mysite/_config.php
Commenting::set_config_value('SiteTree', 'gravatar_default', 'retro');
The rating of the image can be changed by adding a line similar to this to
mysite/_config.php
Commenting::set_config_value('SiteTree', 'gravatar_rating', 'r');
Vald values for rating are as follows:
* g: suitable for display on all websites with any audience type.
* pg: may contain rude gestures, provocatively dressed individuals, the lesser
swear words, or mild violence.
* r: may contain such things as harsh profanity, intense violence, nudity, or
hard drug use.
* x: may contain hardcore sexual imagery or extremely disturbing violence.
