author e-mail

Hello,

First, thanks for this tool!
I try to use it for a “current user” to send an e-mail to an article’s author, but I cannot find where to place author’s e-mail…

I tried this:
define(‘CP_CFEMAIL_DEFAULT_fp_destination_emails’, get_userdata($_GET[‘to’])->user_email);

in cp-main-class.inc.php, but it doesn’t work…

Could you indicate me how to do ?
Thank you very much!
