How to log in?

I registert my selfe, but I cant do /Join !
The only Message I become ist ,The Name Androgan ist not registert ket"
What can I do ?

What do you mean /Join? Also when you registered did it say Rep Mode? If it did, you didn’t register successfully. And if you talk in chat is your message blue or white? If it’s white you aren’t logged in

If you really have successfully registered, remember to /login with the password you typed in when you registered.
