i went on the guilds mumble yesterday but no one was on

i have no friends who play this so wanted to socialize and see if anybody fancied grouping with me to do some leveling (taking me ages to level by myself)
btw i was reading up on dungeons and stuff (remebr this is my 1st MMO) but their all in different race areas. I'm human so i think the first one available in my area is at lvl 40 but in a different race area there is 1 available at lvl 30, how does this work? do i just travel to that area and find it when i'm ready or will personnel story mode take me to different race areas?
