After a very long wait, I am here to bring you some very good news:
The Battle Arena section is now officially open! It's in its first stages of Beta Testing, so depending on how it goes with the users, the rules and systems may change.
If any drastic change is made within the next couple days, I'll be sure to post it here to inform all of you, and as of right now, feel free to use any section of the Battle Arena. Also, please post below if you have a suggestion to improve it, or see a potential problem.
