Continuing the discussion from Discourse plugins to consider:
I haven’t investigated, but it appears we already use the official “solved” plugin. I see that different categories have a setting for whether to allow topics to have comments marked as a solution etc.
Is there a reason to not have that on in general? Seems potentially useful (we have a long discussion on a topic and a solution / resolution comes up… seems common enough). Several times, I would have liked to say that a discussion was resolved and point to a comment that summarizes the resolution.
So I vote we turn on this feature everywhere and only remove it where it seems problematic.
