Took me a while, but I managed to remember it. Along with the (unique) password. It shows 143 contacts, of which 1 is actually online. From skimming through the names I have no idea who more than half of those people are, the rest are family and local friends who I still have contact with.

Contact spreadsheets for teens in Germany back then contained name, address, phone number, email address and ICQ number. We didn't even have a MySpace back then ;)
