I can't find google groups advanced search at all anymore. Where is it?
I used to get archives of groups like comp.unix from around 1983 at work - someone would bring them in on magtapes. We didn't have the capability to generate any postings until a few years later. I think my username was sadg!geccl or sadg!gpt but I can't find anything that old. I was a relatively early demon subscriber, and I the first username I used there was snipped-for-privacy@cucumber.demon.co.uk, but I can't find any of those postings now. I wasn't aware of uk.d-i-y then - don't know if it existed when I started using usenet via demon and snews.
