Kyzor.
I just had the most brilliant idea.
Don't make Kohna an admin/op!
Yeah but see, here's the thing, when I de-op'd myself, I could still use all the admin commands. Perhaps that's a result of my being the host and all, but I won't know for sure until I test it.
Also for christ's sake people, stop telling me which mods to have and not have, it's my damn server, I can do whatever the hell I want. Besides, I already said I'll still frequently be putting up my non-modded vanilla server.
