It used to be, back in the days of white-on-black email and newsgroups, that you were able to keep a copy of everything you did on the Internet. Well, mainly it was because you did two or three things and they all required specific client software that had the option of keeping copies of your contributions, but there it was, you could do it. I, for instance, have a majority of my email back to 1996 — that includes mail from Compuserve, AOL, Eudora, Claris Emailer, Outlook Express, and now Apple Mail. My newsgroup client keeps copies of all my sent messages as well, still. That’s another old, large archive.
