Hello everybody! First of all I want to thank you!
I wanted to make some change in the plugin.
1. I wanted to change the word "name" to "имя" in ru.lang.php 'Name' => 'Имя', 
this is by default but script show another word "Название" see screenshot below
I  tried to change but I did not change nothing.
Q. How to Change this word "Название" on "Имя"? 
2. When I send a message, the recipient can not know from whom the message was received because  there is a small mistake. I mean, that the subject of the message and the name looks the same. So I  decided to make changes to the code
form.view.php Line: 9-10 added
<?php if (Notification::get('success')) Alert::success(Notification::get('success')); ?>
<?php if (Notification::get('error')) Alert::error(Notification::get('error')); ?>
<br />
<form method="post">
    <label><?php echo __('Name'); ?></label><br />
    <input class="span3" type="text" name="contact_name" size="40" value="<?php echo $name; ?>" /><br />
    <label><?php echo __('Email'); ?></label><br />
    <input class="span3" type="text" name="contact_email" size="40" value="<?php echo $email; ?>" /><br />
    <label><?php echo __('Subject'); ?></label><br />
    <input class="span3" type="text" name="contact_subject" size="40" value="<?php echo $subject; ?>" /><br />
    <label><?php echo __('Message'); ?></label><br />
    <textarea class="span7" rows="10" cols="100" name="contact_body"><?php echo $body; ?></textarea><br /><br />
    <?php if (count($errors) > 0) { ?>
    <ul>
    <?php foreach($errors as $error) { ?>
        <li><?php echo $error; ?></li>
    <?php } ?>             
    </ul>             
    <?php } ?>    
    <input type="submit" class="btn" value="<?php echo __('Send'); ?>" name="contact_submit"/>
</form>contact.plugin.php Line: 43 added
$name  = Request::post('contact_name');            
$email = Request::post('contact_email');
$subject = Request::post('contact_subject');            
$body  = Request::post('contact_body');Line: 63 added
$recipient = $recipient;
$name = $name;
$subject = $subject;
$header = "From: ". $name . " <" . $email . ">\r\n";
Line: 79 added
->assign('name', $name)
->assign('email', $email)
->assign('subject', $subject)
->assign('body', $body)
->assign('errors', $errors)
->render();Now I have additional field "Subject" , and Now,  the recipient sees the  correct Name and Subject! 
And Thank You Very Much again! GREAT CMS EVER I SAW!
