Question: We've discussed this in comments in a number of different topics, and it's come up time and again, so we should explicitly cover this:

Are questions about stage combat (or re-enacting [Ren Fair, SCA, Civil War?], etc.), even if the intent is to adapt a martial art to stage combat, on topic?

Answer: 
I largely agree with Ho-Sheng Hsiao. I think that the original question, as asked, is relatively problematic, and while I recognize the need to not let us branch too broadly, I am uncomfortable with the idea that the *purpose* of the practice matters relative to what the practice is. So if you are practicing taekwondo for money as a combat sport, I don't see that as different (for the purpose of this site) as practicing for fitness, as practicing for self defense, as practice for self-discipline or personal improvement. You are practicing a martial art. "Why" is not as important. I think that a "martial arts SE" can be somewhat broader than simply the question of "things that go into specifically traditional martial arts."

So while I don't think stage combat, as a genre, is appropriate here it is easy to imagine stage-combat questions that might be appropriate. So long as they focus on the *martial art* side and not on the *acting* side. 

Asking how you adapt a martial art to the stage is going the wrong direction. But asking something along the lines of "we are trying to make this stage combat scene (insert youtube video or EWMN schematic) look like a more realistic fight, what can we do?" could very well be on-topic.
I believe talking about stage combat would give better answers on this Q&A site. When you want to emulate a certain fighting technique, there are visual differences on how you stand, throw a punch, and kick.

The advice that could come out of this site would give someone more detail in how a move is done, or what happens to your opponent when you hit him in a certain way.

I know some will complain that you don't know stage combat, and due to that lack of knowledge, not be able to help; what you can do is help with the visualization of a move, the body mechanics required, and what about that move makes it hurt someone (which means you know what to alter).
