Just reading the top post seems good enough for the time being from what I glanced over. As for actually starting a fight with someone, I'd just go to the arena chat thread and challenge someone: http://www.roleplayerguild.com/topics/78452-arena-chat-thread/ooc
@Aqua Fire I've only got one arena character right now, but I have ideas for a couple more. I'm also new to arena but I have done a little. I'm up for a fight if you are.
Edit - Well I just finished one of the ones I've been working on, so there's also him if you'd prefer.
