I was looking at some old questions and ran across this one about the Boston Tea Party. It's a good question and it has a good answer, but it really belongs on History.SE rather than Politics.SE.
The question is almost 5 years old at this point, so should it be migrated? Is there any point to dealing with now it given its age?
If the answer is yes, how do I go about doing that? Flag it or VTC?
What's the general policy on this kind of thing?
