How do you do this?

How do you make yourself superadmin on GMOD Murder. I really would like to know.

First: do you have ULX? If not, get it.
Second: In your console, type “ulx adduser playernamehere superadmin”

You need to type rcon_password “password” then rcon ulx adduser username superadmin

RCON should really be disabled. Not to mention that he never said he was using ULX.
