Groups (Default Raid vs. Organized Raid)
When you join a battleground, you'll be placed in a raid group automatically. However, if you join the battleground while already in a preformed raid group, you will remain in your preformed raid instead of the default battleground raid group. If you're in a battleground and you want to join your guild or another group's battleground team (commonly called "premade" or "organized team"), you can still do so. Just have them invite you while you're already in a battleground. Then when the game starts, you'll be plucked out and will join their battleground. Pretty cool!
Communication
Players communicate in the battleground channel. To type in this channel type: "/bg text." You can set the color for the text for this channel as well. To find the color right-click on the General chat window name/tab. Go to Channels -> Party. There, you can set the color for both battleground and battleground leader.
Battleground Holidays
Battleground "holidays" exist for Warsong Gulch, Alterac Valley, Arathi Basin, and Eye of the Storm. Holidays occur during most weekends, starting on Thursday night at midnight server time and continuing until Tuesday morning. During a holiday, emissaries from that battleground will be found in the major cities, and honor/faction rewards for performing objectives in that battleground are increased.
The order of the holidays is: Alterac Valley -> Warsong Gulch -> Arathi Basin -> Eye of the Storm.
Daily Quests
Daily quests have been added targeting a random battleground for that day. Look for Alliance Brigadier Generals and Horde Warbringers near your faction's battlemasters in all major capitals.
Battlegrounds: Instant Honor
There is a repeatable quest called "Concerted Efforts" which allows you to turn in four Marks of Honor for a chunk of honor points. One mark is required for each battleground: Alterac Valley, Arathi Basin, Warsong Gulch, and Eye of the Storm. If you have a store of marks, you can turn them in over and over to gain honor to buy an item. You can find this quest at an NPC at the battlemasters in major cities or Shattrath City.
