At this time that functionality is not supported.
You could setup a forward rule of some kind on whatever e-mail client/server you have receiving admin messages now.
Or you could edit wp-statistics\schedule.php, on line 152, replace the “get_bloginfo(‘admin_email’)” part of:
wp_mail( get_bloginfo('admin_email'), __('Statistical reporting', 'wp_statistics'), $final_text_report, $headers );
with a list of addresses you want to send to (see http://codex.ww.wp.xz.cn/Function_Reference/wp_mail for details).
Of course you would have to make this change each time a new version comes out.
I’ve added support for a list of e-mail addresses to send to. It will be in the next version.
Sounds good. Also thanks for the response.
