I just made an edit to this question, and then noticed that it was marked as a duplicate . I couldn't however, see the duplicate notification at the top of the question.
Diving in to the revision history, I can see that the OP deliberately removed the markdown of the duplicate question* (which pointed to: How can I identify a counterfeit Xbox 360 controller?)
Should I add this back in? or should we reopen and reclose the question so that the new duplicate markdown (the uneditable one) kicks in?
*For those that don't know, the 'Duplicate' message at the top used to be part of the question body, and still is on a lot of old questions marked as duplicate
