Once the plugin is installed you can use the settings interface to set the length of the standard appointment as well as configuring the following items for the confirmation email:

<li>The BCC address to copy in for each confirmation email.</li>
<li>The prefix for the confirmation email subject.</li>
<li>The body of the email message.</li>
</ul>
Appointments can be added by entering the date and time and then clicking ‘Add Appointment’. To delete or reset an appointment select the checkbox next to it and clicking the appropriate button.
