No technically not, although there is a plugin that isn’t active that allows the mods to run SQL queries on the DB, so I guess that could be enabled and then we could get that data.
I’ve turned on the ‘solution’ thing for this forum and the Site Feedback one now. This means the person who started a thread can mark a given post as the ‘solution’ (mods and admins can do this too) and these will then show up in the ‘solution’ bit of your stats.
