just be nice to people and they will be nice to you too. find a friendly guild that will not just benefit you but also benefit them(somehow). dont expect people to be nice to you all the time becasue like in real life, there are some jerks here too lurking around.
also, dont beg for money or gears as people will just ignore you. people here in general dont like newbie asking for gears. i see this case almost everyday. im not telling you that you will do it, but just beware.
