I've noticed that oftentimes the questions that are closed are asked by members with few reputation points, many of whom have only recently created their accounts, and are posting their first C.SE questions.
While closing questions that have been answered before and are not worded in a way that presents a new angle on the question seems reasonable, would providing something more of an explanation beyond the one to two sentences mentioned in the text in the "closed by [users] for ..." comment be more welcoming to new users?
Speaking as a new user myself, if the goal is to grow the site and provide a valuable resource, then it seems like responding to some new users' first efforts to contribute by closing their questions and providing only a terse explanation for doing so may be counterproductive. To someone new to the site who is not yet familiar with the community guidelines, it could easily be interpreted as a summary rejection from the moderators, even though that is not what the moderators intend.
If any think that such is the case, what would a more welcoming way of still closing repetitive questions be?
