I wouldn’t want to remove posts, but it might be interesting if search and related topics defaulted to within a year or two instead of all time? Do you know if it’s possible?
Also I think it’d be good to allow for others to at least “flag” a post as solved in a way that you or a small group of moderators could double check and confirm and apply. The original poster could easily remove the few false positives, if any, that arise.
I found the “solved” plugin for discourse forum at very beginning. We have this plugin enabled at day 1 when cocos2d-x Chinese forum migrated to discourse.
@stevetranby we would not delete or archive or otherwise change how the topics are retained on the forums. Just try and make possible solutions more identifiable and allow folks wanting to answer questions to see what topics are not yet solved.
