I run a Discourse installation that hosts a number of technical support documents in addition to other discussion. We have a problem with our users finding really old (several years old in some cases) dated content that has been superseded by newer documents but as everything looks the same they may not notice they’re reading very old and dated content.
I did find some old discussions related to auto archiving but not specifically to this use case. Specifically I’d like there to be a distinction between archived and obsolete content. (Some discussions What would be the best way to mark this dated content as obsolete? Does this have to be a manual process?
In an optimal situation there would be a plugin or some other way to give topics an expiration time or date (ie. “this content should be marked as obsolete after 180 days since last edit”) and after a topic would be marked either manually or automatically obsolete, it would display a clearly visible warning in the lines of “This topic has been marked obsolete as it is 2 years old. Please use the search to find for up to date information on this matter”.
