I got the email it says : Congratulations! You’ve been selected to be a PBE tester! You’ll help us root out problems, test ideas, and work with our development teams to build new stuff for upcoming League of Legends releases. But when I try to create a account but the website show something's gone hextechnically wrong ,error 500.
I hope someone or the office worker can solve this problem.
