Trouble is, caught for what? If the site lapsed, picking it up is trivial, and done all the time. Robert has no more claim on the site than Sylvia does, beyond his having originated the name and paid the fee; if it lapsed while he was ill, there's likely not much that can be done about it. This is not classic cybersquatting; the site is not anyone's registered name (unless Robert incorporated, which I doubt). Someone - and I blame myself as much as anyone for not bringing the subject up; heaven knows I thought about it - should have been looking after it. If the owner is "cool", perhaps we can buy it back, but with the traffic it had going to it I imagine that might be steep. We're lucky its not a porno site by now.
Let this be a lesson - no one knows the hour or the day (sorry for the biblical reference there). Get your affairs in order, and make sure they have continuity when you fail, as ultimately you must. Gees, where's my passwords file?
Recovering the pages is not a problem; I'm sure Robert has them on his home computer, just as I have one for the sites I webmaster. The problem, as erlando points out, is the site name itself and it's search recognition. Perhaps Google might help out? It would be nice to know if that's possible.
