When you login: 

Click your avatar in the top left of the screen, click the info tab and you'll find your player ID there.  

Thanks I got that but I need user ID.  Its for the voting thing the greatest knights in Teleria.  It asks for user ID and player ID.

one of them is in ur profile page like dhorn said, the other name is ur display name that ur clan see you as.

name by your avatar/profile pic in game = user ID

the number in the info tab where you can hit copy ID = player ID

Thanks guys, got it figured out.  I wasnt copy and pasting the used ID....DUHHHH.
