how to switch servers?

yes there is always those wishing to play with friends. if they compklain they obviously dont wish to play with there friends that much

It would be nice because my friend started playing this game and was going to refer me when he finished task 5 but since he was on a different server he was unable to do that! So now i lost my referral and the prestige bonus!

Friends who refer you don't have to be on the same server as you, as long as he enters your name in the referral box when he does task 5 you get the rewards (when he levels up)

Well I was sitting right next to him and we tried putting my name in like 4 times and everytime it said i didn't exist

Then you must have been putting the name in wrong....
