I recently posted "Did medieval European monasticism provide a release from certain societal pressures?". It has been suggested that it would be a better fit for the History Stack Exchange (which seems likely to be true).
I posted it on Christianity because I was working toward the Curious badge (I have other questions that I have not gotten around to asking, so this one is not critical) and I dislike "userXXXX" marked posts and did want to "join" another SE where I would rarely participate. (It is bad enough that I signed up for Programmers and UX in order to upvote some posts! At the time I thought I might eventually write a question or two for Programmers.)
Assuming it is a better fit for History (and a quick search there found no questions on monasticism, so it should not be a duplicate) and that migration is appropriate, how should I proceed? It is technically not off-topic (I think), and it might require moderator action to migrate to History (since that migration path is probably not standard).
This answer by Shog9 on Meta Stack Exchange seems to hint that migrating might not be the best choice for this type of question (on topic but less on-topic than at another site). However, that part of the answer seems to be more in the context of being inappropriately exclusive and not in the context of trying to get the best answer possible for the question: "Don’t hit them over the head with your scope, help them tailor their question to fit into it".
