I've udpated the SURBL web site to use frames and have freshened the content slightly. Please let me know if you spot any broken links, etc.
Also added "An Open Letter To Operators Of Redirection Sites" in which we try to appeal to redirection sites to deny their services to spam URI domains (e.g., spammers' web sites). Redirection sites may become an increasing problem if we're successful in blocking spams with their sites directly linked.

Comments, revisions, questions, suggestions on any of that are welcomed.
Cheers,
