What special features do a GameMaster have?

[RamGuy]

Hi,

I have just signed up to become a Game Master in World of Warcraft.
But if I be chosen, which new features will I get?

Is there any sort of guide or something on the web, any please that discribe the features of the GameMasters and how they use them? (like how to spawn to a point and such...)
If there is, please post the link to the site here! Or PM me about it.

I hope someone can help me.
