I'm looking for a plugin that will redirect visitors from certain IP addresses (or address blocks) to an alternate home page. So far I've only found IP-banning plugins, which is not what I want.
(Also, I'd just like to say - while I'm on the subject - that trying to ban problem users by displaying a big nasty "You're Banned!" message tends to be counterproductive and only emboldens them to try and come back using a different ID. Banned users should not even realize they have been banned. Don't know why plugin authors think "You've been banned!" is a great message to display...)
