Question about serversFollow

As you may have noticed from other posts; Im quite clueless about how all the servers and stuff work.

Are you always logged into the same server, and how do you go about finding out which one?? Am I right to assume that if the same people are logged into the same server, you will be with the same people all the time.

I think i really need to find some really low levels people to start the game up with rather than just myself. Im sure there are new people out there somewhere.......

Sorry, I noticed I clicked on the wrong forum :P
