Something I've noticed is that archived discussions are visible of you're not logged on to ACC, but when you log on and try clicking on one, you're just redirected to the main forums page. Why is that? Are logged on users allowed to reply to archived discussions for some reason, so that's why you're not allowed to see them when you're logged on to prevent new users from bumping really old threads?
Well, sometimes when Googling things related to Animal Crossing, I get results for archived ACC discussions. And it's not like they're not labeled as such either, you can see a big red label saying ARCHIVED. After logging in and then trying to click on an archived discussion, I get redirected to the main forums.
