1) Took a look a the domain (illuminations.nu) today and it's set to expire in July 2010. Good news! I don't have to do anything there to get the site up and running again.
2) Called the hosting site (whatever you call it) and even better news: even though everything was booted off the main server, two backup copies of the files were made. Eeeeeee! The files have now been "packaged" as the rep called it, in case they do another purge while I'm trying to get this taken care of -- and believe me, with the luck I've been having lately, that's exactly what would happen.
When I told the guy I had a new email account (cuz I do), he asked for it and then said that I'd have to provide proof of ID. No problem. EXCEPT...and you can probably guess where this is going...Catherine is still listed as the owner.
So if anyone out there knows Catherine and can get in touch with her, please ask her to get in touch with me. I sent email to her catherine4654 address as soon as I saw the form with her name on it, but so far I've had no response. I know that she travels extensively for business sometimes, so if there's another, better email address out there and you know it, please let her know I'm looking for her. :-) Thanks!
Now for a cheesy exit line: Thank you, and may God bless.
edited to add: We have contact!
