The main things I'd like feedback on:
-Does it read smoothly?
-Do the collapsibles provide ample backstory?
-What things can be completely expunged from the article?
Final Note: I couldn't find a proper image under the Wikimedia Commons that displays a standard American version of -3, leading me to make that small note in the article.
EDIT: The image is listed under CC Attribution 2.5 Generic (CC BY 2.5). Is that considered okay under site regulation?
