I don't think I have anything 90s that still works. I remember ordering from Amazon in 1999 or earlier but my current account has my first order from early 2002, so I must have recreated the account for some reason. Ebay is about the same time, 01/02. My Yahoo email is probably 2001. AIM would have been 98/99 but they killed it. ICQ would have been earlier but I haven't logged into it since 2000-01 probably, if it still exists I wouldn't know the password. Actually Slashdot would have been 98 I think? (six digit UID starting with 100xxx; I'd have gotten 5 digits if I'd created the account a week or so earlier :P), but I went through and did the "delete my account" request there maybe six months ago.

Can't think of anything else that would still be around from before about 2001.
