Adding Mail Compose Block to Profile

How would I go about adding a compose message form to the users profile page?

Any ideas?

Do I need to do a service call?

 Hello

You cannot use Service Call because mailbox is not a module. It's a system feature. So, you need to create a PHP block and call getBlockCode_ComposeMessage function from templates/base/scripts/BxBaseMailBox.php file. The code should looks like the following

$aMailBoxSettings = array (
'member_id' => $this->oProfileGen->_iProfileID
);
bx_import('BxTemplMailBox');
$oMailBox = new BxTemplMailBox('mail_page_compose', $aMailBoxSettings);

$GLOBALS['oSysTemplate']->addCss(array('mail.css'));
$GLOBALS['oSysTemplate']->addJs(array('mail_box.js'));
return $oMailBox->getBlockCode_ComposeMessage();

Fantastic, many thanks AntonLV.

For any others with a similar problem, use Anton's code above but add this:

$aMailBoxSettings = array (
'member_id' => $this->oProfileGen->_iProfileID,

'recipient_id' => $this->oProfileGen->_iProfileID
);
