                Introduction:
                <textarea class="widefat" rows="10" cols="20" id="<?php echo $this->get_field_id('text'); ?>" name="<?php echo $this->get_field_name('text'); ?>"><?php echo esc_html($instance['text']); ?></textarea>
            </label>
            The subscription form is created according the subscription panel configurations and appended at the end of the introduction text. If you
            want to place the form in the middle of introduction text above, use the {subscription_form} tag.<br />
            You can even create a full customized subscription on introduction text, it will be detected and the standard form not inserted.
            Just add a &lt;form&gt; tag with wanted newsletter fields (see documentation on custom form building).
