Newbie in server

Hello there,

I dont know how to register in the server. It doesnt allow me because of the password doesnt match with the confirmation password… but im new so… i dont understand what does that mean…

It means your failed to type your password correctly one of the two times.
To register you use:

/register <password> <password>
(replace <password> with your password)

This is to verify you typed your password correctly. You either didn’t type you password a second time or didn’t type it right one of the two times
