The question What is the correct form in this case? was (quite correctly, imho) closed recently. I posted a comment asking the OP to edit in further details, with a view to having the closure reviewed.
But user Community has locked the post, so the OP can't revise his question.
Is this a bug? I can't see how it could be a "feature".
EDIT: Older and wiser, I've deleted the "bug" tag from this question. It's a sensible design feature.
