Thanks for all the helpful posts folks

I'm new to the game and relatively new to mmo's so bear with the noobie. Basically i chose a pvp server but am still unaware of how it works. My q's are where does player killing take place e.g only in these warzones or in certain areas of the game . Do I have to be a certain level before I can take part and do I need special equipment. Can someone with more than 10 brain cells please explain :S
