Jeff has a bunch of domain names and websites, but the person who set them up has disappeared. Now he has to renew the domains, and he can't. Leo says that what is likely happened is that the guy who set up the websites, listed himself as the point of contact. And with domain hijacking, registrars are reluctant to transfer them, no matter how legitimate the story is. The only thing he can do is hope that the registrar gives in and changes the point of contact to him. He can "scrape the website" to get all the content and then rebuild it with a new domain name. There are apps that will download a website for offline use. But he won't get the code. Just google Website Downloader. SiteSucker is one that Leo has used. There's also SiteFetcher.
The other option is to put a watch on the domain, and once the domain is officially expired, he can get it back. Depending on how long ago the domain was renewed, it may take up to a year. Since it's WordPress though, change the password, and then go into the site settings and forward the blog to a new address. That can be done right away.
