The Contact module allows site visitors to send emails to other authenticated users and to the site administrator.
Through personal contact forms users can send one another e-mail. And through site-wide contact forms, users can send e-mail to arbitrary email addresses, such as the site maintainers.
With either form, users can specify a subject, write their message, and also have a copy of their e-mail sent to their own address. Through contact forms, users allow themselves to be contacted yet keep their own e-mail addresses private until the message is replied to. As an administrator, you can enable or disable the contact module altogether.
As a user, you can also enable or disable your personal contact form if that option has been provided. When the form is enabled, a contact tab is displayed in your user profile, for everyone to see. (Privileged users such as site administrators can contact users who have turned their forms off, as they can access their user account email addresses.) When you visit your own profile, the contact tab is not displayed. However, it is displayed to other users (if it has been enabled).Read more
