I was just curious as to what is the specific amount of time a thread needs to go for without getting any posts on it for it to be Auto-Locked due to inactivity?
This time is the same across all sections correct?
The auto-lock applies to nearly every forum (some exclusions, mostly hidden forums for moderator use). It's possible I may have missed some, if added recently. The period used for "Auto-lock" is 90 days.
The For Sale forums have separate locking rules (a few days after paid period expires) and is auto-deleted after 2 weeks of inactivity (I think that's the current setting). There's also a 2 week (I think) auto-deletion of the Off-Topic forums.
