Scott, Congratulations about the beatiful work! We got FreeBSD since 1994 (Version 1) and have the confidence in use all new releases in production in lot of hosts widespread over large states areas here in Brazil. In all of this time we had some insignificant problems in version 5.1, only. So, we know the great work of a great time. Thank you for take the opportunity to use FreeBSD now and in the future.
