I stumbled across this question and I'm unsure of how to handle this.
This question was answered in the comments, so if this was the only "issue" - I would normally just comment to the users involved to post an answer/accept the answer.
However, this question seems to be something that StackOverflow can answer. There are multiple questions that answer this. This one for example.
I want to be a contributing member of this Site. So what would be the correct action (if any action at all) to take on this question?
