Forums Developers mIRC- Locking client to specific server?

So there's no way to disable the server change function? I'm guessing it's something embedded in the EXE cause I haven't found it in the DLL or INI files yet. It would be great if I could get mirc to not recognise the /server entry and the add button (most of the students probably don't know about the /server usage).

I'm probably good enough with just removing the serverlists, cause unless the student is up to no good I don't suppose they'll be trying to find the server names anyway.
