Extension:ContactPage

The ContactPage extension implements a contact form for visitors. It creates a special page "Special:Contact", which is similar to "Special:EmailUser", but it has a fixed recipient, and may be used without registering.

Further customization
To do this add ...
 * Adding a link to special page "Contact" to the footer of your wiki (< 1.37.0)
 * 1) ... the following code without changing it to your "LocalSettings.php" file:
 * 1) ... the URL of "Special:Contact" to system message  and
 * 2) ... the label for "Special:Contact" to system message.

See HTMLForm and related pages for more information on the possibilities available to create more complex forms.

Issues
Users of some hosting providers such as SiteGround and Amazon SES may get a PHP mail error or one that says that the FROM email address is not configured in the server, despite  being configured correctly and other email functionality working as expected. A fix for this issue is described here.
