Eric, would you consider letting "super-users" at a site unsub a LIST from that site? You might reserve the userid of who you considered a superuser and not let such a person subscribe. That would quickly pick up a misallocation of the id (I hope). Dave Dave Gomberg, role model for those who don't ask much in their fantasy lives.
