We usually discuss whether certain type class of question is on-topic. After discussion some types are, some others aren't.
But this doesn't determine all the rules. Some questions belong to both classes, for instance:
Have been trying to translate this.. hoping it some info of a great grandfather belongs to "translation without effort" and to "Read old handwritten Text"
Sure, some agree (and so I have to agree) that old handwritings question are on-topic. But the question is also to translate.
What to do in that case?
