I have an old quiz from years ago which has since been archived. I'm wondering:
What does archive mean?
What's the reason for archiving?
Can the quiz still be played/ easily found?
Thanks for any insight.

Archived just means that you can no longer edit it yourself. In the first few months after a quiz goes online, when corrections are most likely to be sent in, players are allowed to make amendments themselves. The quiz is then archived, so only an editor can make changes. In all other respects, there is no change to the quiz and it can be played normally.
