I find that many technical (or at least, problem-oriented) questions are in fact best presented using a noun phrase (or present participle phrase) as a title, rather than something which is grammatically a question.
There are thousands of examples, but here is a random selection from questions relating to arrows:
Two-way arrow as when defining adjoint pairs
Gaps between arrows and labels
I think it's easy to see why: preamble such as "Is there are a way to..." or "How do I..." is usually fluff that distracts from the task of identifying the problem.
Do other people find this a useful rule of thumb? If so, should it be in the guidelines?
