So, there is a question that has 1 answer, which the user has already accepted. For me the answer is not bad. It is similar to what I would answer but has no Backing.
Funny enough, it has several upvotes, I always fail to understand the logic behind that. In any case, originally I was going to answer the question but when I saw this other anwer that was similar, but without backing. So I didn't post my answer, because I wasn't sure if I was going to add too much value. I waited several days and it still has no backing.
The user is new I think, and since I am not a moderator I didn't want to seem rude telling him to add backing or so, I don't normally do those things, plus several people upvoted the answer. Maybe is is so common that the backing is obvious. Like it obviously comes from his experience? Or maybe it is there and I am not seeing it.
In any case, would it be all right in these circunstances to post a similar answer, offering my backing, that is my background and some additional advice?
