The management and admins would everyone to know that reports are A-OK,
if the original puzzle post of a said vehicle was solved at least 12 months previous, preferably longer than that.

Posting a link to the original puzzle is not discreet.

Once the repost puzzle has been solved, they should, of course be merged
