I've followed what goes on here for a while, and wanted to suggest an army list, so I finally signed up!
I'm Nathan, I am from the Boston area, a 30-year-old math teacher. My other hobbies include dancing and occasionally writing short stories.
I first discovered Warhammer
40K when I was 13, and after a very long hiatus, returned to the game about 3 years ago. With the resources of an adult, I collected significantly more figures, but never collected any army other than green marines. They've been Dark Angels, Salamanders, and now even Raptors.
I even enjoy losing when I feel like I learned.
You can find the army list I proposed, a mix of fluff and cheese, at

I'd appreciate advice and comments.
