Anybody playing WoW (World of Warcraft, for the nubs)?

[stabn]

Just got it for Christmas so i'm trying to decide what server to start on. I think i want to go with a Horde race (alliance sucks!), other than that i have no clue really. I don't know much about the game other than it's a MMORPG with a warcraft theme. If anybody is playing and has race/class/server suggestions let me know. Anyone decide if it's really worth the 15 a month? I think i might just play it for the initial month and quit before they start billing my ass.
