Shurikai. I knew nothing of D&D and filled out the whole sheet in a couple hours, while also understanding stuff, thanks to the assistance on the IRC.

Edit: While in battle, how do we know who's where? Isn't it going to be hard to see if someone is covered from range attacks, or how far they are from the enemy and so on? We need something like a board that everyone can edit. Maybe something like googledocs with multiple pictures. One being our current ship, one being the enemy ship and all the others the characters and NPCs.
Just a thought.
