RCON isn't really much use at present

[VariableVixen]

As I write this, there are only two rcon commands: announce and announcerestart. You can't list players, you can't kick/ban/unban players, you can't check server status... you can't actually administrate the server outside of sending global chat messages to say that you're going to reboot it.

If the devs see this, please implement commands like listusers, kick, ban, unban, addtime, setadminlevel, etc in the rcon server. Right now, it's very nearly useless.

Honestly, why even implement a command system if you don't also implement the most basic of commands?
I would suggest finding the website the developers have told us will be their suggestion outlet. That way you have the best chances of reaching their attention.
