There seems to be a general consensus that questions (like this one) which ask about how to fit your text within MLA (or other stylebooks) are off-topic, since both 'what MLA mandates' and 'the way your professor prefers papers set out' are valuable advice to the student, but cannot be classified as 'English Language & Usage'. Often the questions are welcome on Writers.SE, or occasionally on Academia.
However Chris, the OP on this question, points out that the distinction is unlikely to be clear to a newcomer to the site, particularly if he has discovered that ELU has a specific mla
tag.
I don't dispute that the tag has been valuable in some cases; but is it still valauable enough to be worth the confusion? Or is it time to retire the mla
tag,and possibly add a sentence to the help along the lines of "specific formats are off-topic here"?
