Tips for New Players

DON'T BEG
We have money because we go out and earn it by doing quests and running dungeons - not by sitting around in cities and inns begging for it. If you go out and complete your quests your money will accumulate quickly.
READ YOUR QUEST DESCRIPTIONS
If you carefully read the quest description you are usually told exactly where to go and what to do. Don't be lazy.
NO MEANS NO
If someone declines your invitation for a party, guild or duel do not spam them after they have declined. Don't abuse or insult them in private chat either. If you feel rejected you are taking it too seriously.
NODE RAGE
You don't have automatic rights to every node, herb or chest that you see - this isn't an offline solo game. If another player is fighting a monster near a node/herb/chest you shouldn't rush past them while they are busy to steal it.
BE HELPFUL - BUFFS
Buff players that you pass on the road - the tiny mana cost of a single buff will replenish long before you reach your destination.
BE HELPFUL - MOBS
If you see another player in trouble consider helping them out by healing them or taking a few swings at their monster. However, make sure the monster's title bar has turned grey so you don't steal their kill.

ASK BEFORE OPEN
Ask a rogue to open your lockbox before you interrupt them with a trade window and an expectation that they will automatically drop whatever they are doing to help you. In fact, always ask before opening trade for any reason.

WE DON'T SPEAK COMMON
Horde characters can't understand what Alliance characters /say to them - their default language is Orcish instead of Common. All they see on their screen is gibberish. Also if you custom emote they will only see you 'making strange gestures'.
