This comes up every time I log into a server. How do I solve this?

to register. do /register password password, so for example. say you wanted your password to be : hello123

you would do /register hello123 hello123

Wan is spot on! Another example is /register apple apple.

It's literally telling you what to do xD Just type /register (password) (password again) make the passwords anything you want, but be sure to remember it.

It's basically like this. Your forum account and ingame account aren't in collaberation, so even though you are registered on here does not necessarily mean you are registered ingame. Unlike many games, you actually register in the game.

So where it gives you the message you are going to have to register your account.
Simply type
/register <Password> <ConfirmPassword>
this should register your account to the server. Now that you are registered, you must login every time you join. To do this type
/login <Password>
The password being the same as what you registered with, of course.
