This setting is described as:
When someone starts replying to a topic older than this many days, a warning will be displayed to discourage the user from reviving an old discussion. Disable by setting to 0.
I’m thinking running threads of great age, like a “Introduce yourself!” pinned topic or a game of some sort. Will users get warnings for replying to a topic that has a creation date greater than (n) days? Or will they only get the warning when replying in a topic that hasn’t been posted in for (n) days?
Two very different things. I’d much prefer a setting for the latter than the former.
