I know the website well. Something is up with the site because I'm seeing a "account suspended" message on the main page. That is unusual and makes me think the site was hacked. I tried accessing it using https: and received a browser warning that the site was considered dangerous and the certificate has expired. Another indication the site was likely hacked. I successfully pinged the server so that is not the problem.
The domain was registered at GoDaddy but privacy is turned on so the owners name and contact info is not made public. The odd thing is that it shows the domain name does not expire until 10/1/2024. This means the website should be online.
Sadly, without access to the server (name and password) you cannot retrieve the information. It is most certainly in a php or sql database on the server. Ranger95 did a lot of typing to compile the list of names and histories into a database, even if the info came directly from a book. But, he also added personal histories that people shared with him over the years.
Thank goodness for WaybackMachine. It is doing just what it was meant to do so nothing is ever lost. The info should remain at least until the zombie apocalypse.
