When I tell the Asteroids@Home login procedure that I have forgotten my password but remember my username, I get these messages:

Deprecated: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead in /home/boincadm/projects/boinc/html/inc/phpmailer/class.phpmailer.php on line 1909

The email arrives and allowed me to reset my password, though.
