Who ever told you that you can do that is wrong. You can not connect to a mud as a god unless your character is a god or you just happen to be in the relevel code, highly unlikely. I've coded on several muds with different formats, connecting and just "becoming" a god isn't possible.

Only ways to be a god: 1) be made a god by one of the others, 2) your name is in the relevel code, 3) you have the shell acct username and password to add yourself to the relevel code.

Obviously your not any of them, don't try or your just going to get banned or worse.
