Hi,
I have a server with zombie mod, some people are changing names and steal XP point. Is it possible to make plugin who makes that: when person who enter my server first time must choose a password and when he enter my server second time (in this same nick) he must write password (unless kick). Password should be written in file (the plugin would make file with nicks and passowrds [and add people] automaticly). Have you got any tutorial or other help how to do it ?
