Way back machine link for those who want to take a look.
This is very specific and probably only remembered by a handful of norwegians, but there used to be a website called Bamsemums (.com) from candy company Nidar, where you could join a flash based hangout that allowed you to chat in chat rooms, browse registered users, make "bulletin posts" for recipies, and you also had your own apartment you could decorate with furniture that you bought with money I believe you got from doing like, these "exams" (quizzes).
This was back in like anywhere between 1999 - 2004. I think the site still existed around 2005 - 2007, maybe. But it was def peaking around 2000 - 2004.
There's fragments of the website on Wayback Machine, but I'm not savvy enough to actually explore the lost flash site, if it's even possible.
