Probably not the most exciting thing in the world, but I noticed today that nic.im (the Isle of Man registery) has changed the address of their whois looking. If you want to update your jwhois.conf file to use the new URL, replace the current nic.im section with the following:
"www\\.nic\\.im" {
http = "true";
http-method = "GET";
http-action = "/public/whois.mth";
form-element = "domainname";
}

As it’s a web lookup rather than a proper whois server, you will need either elinks or lynx installed. Also you’ll get some extra shit back (like headers and links), but hey you can’t have everything!
