Sure? If you are reading at home and at work then are you not already subscribed twice anyway? We can constuct all sorts of interesting "edge cases" where this change (or any other change for that matter) will inconvenience somebody.

(Spam databases are very poor at best - FreeBSD already uses a very large one) M -- o Mark Murray \_ O.\_ Warning: this .sig is umop ap!sdn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
