I just learned that the Enlightened badge, is for the First (in time order) answer on a question that is also accepted (with 10 upvotes).
Up until now I thought it was for the First answer for a user that got accepted (with 10 upvotes).
The current text is
First answer was accepted with at least 10 up votes
The First answer for a question was accepted with at least 10 upvotes
though other suggestions would be fine.
