So, I'm very new to Arena, (the only thing I've put interest in hasn't moved in weeks) and want to be a part of the Arena. I just don't know how to start or what to do. It doesn't seem like there's anything going on, since most of the recent iChecks are days/weeks old at earliest. 

tl;dr New to arena. What do?

Arena regulars seldom post in the interest checks, since most of the business goes around in these two threads:

http://www.roleplayerguild.com/topics/78452-arena-chat-thread/ooc?page=173

http://www.roleplayerguild.com/topics/79678-rpguild-ranking-headquarters/ooc?page=70

You can ask for a regular fight in the arena chat thread, or sign up for the rankings and look for ranked battles in the headquarters. A character sheet and basic understanding of what roleplay combat is like will all you'll need for that.
