At the request of various people, we had made forums for each BG... kinda. The way it works is that there is one forum containing a thread for every BG/Bracket combination. The threads all will be titled REGION-BGNAME-BRACKET, making it possible to have a quick way for you to find your BG forum by typing in the name.
Example: http://www.arenajunk.../Bloodlust/5v5/ will take you to the thread for Bloodlust 5v5. If no thread exists, it will take you to the main BG forum category where you should create a thread titled REGION-BGNAME-BRACKET.
If you look at your nav bar, there are quick links for you to get to all of your BG forums.
Hope this helps you schedule times to play and talk to our people in your BG. If you have any other suggestions for how this should work, please feel free to let me know.
