Action is very broad, though. What kind of action? Most kinds, really. Preferably involving swords or knives. I'm not too knowledgeable when it comes to ranged fighting. Swords and knives is also very broad, good point. Well, I'm well-versed in most eras. I've read treatises by 15th century Italian masters and Viking age germanic masters, so yeah. You're in (somewhat) good hands.
While reviewing action, I will consider both the technical aspect and the emotional aspect. So, if you feel that you've written a bit of action, but would like an opinion about it, I'm the guy to go to
Cheers.
Edit: this also applies to action in SBs. Naturally, this will take place in PM.
