Good to see you back, koan.
I think that the index.html or equivalent is simply missing for the
www.oesf.org addie. I did some research yesterday and wrote a long post that disappeared, but I think that if someone in addition finally has ftp access, while shell access would be more efficient, it still may be possible to remove the bad code rendering the oesf.org inaccessible.
Will try to rewrite that by tomorrow, too busy today, My hunch is that the wiki pages may actually still be at archive.org but hidden. And I think that even with link rot, elsix.org is still valuable, quickening taught me a long time ago that searching there, I would at least then have the correct package name to search the net for, and often could find what I needed somewhere.
What I have been hunting for is the link to the main wiki page, and not sure what it is! Anybody know?
I did save copies of two wiki pages on my site years ago, the ones about sd/cf cards, but I don't think those have the wiki url itself.
