Sadly, this is something that's going to happen more and more.
In my (luddite) case, stuff that is related to builds and suchlike is sourced from my apqw69 account (or occasionally from pd49) on pipex. General stuff just to illustrate a post is on my.gn15.info. All the material on my two major accounts will (if everything goes right) survive my demise in the same way that hopefully the large handful of lists will be informed: a group of us who share information about design and coding issues have cunning plans in place, largely because we had to rally round about ten years ago and help the widow of the first to fall, who had no idea which lists and sites were involved.
There will still be a problem, though, because the image urls will change. Emrys gave me a handy dandy search thingy when I was re-ordering the apqw site; this needs doing again and I can't find it any more, but it was really useful and might help others - for various reasons, not just the ultimate one.
