RtCW Omnibot

Hello,

I wanna make a server with a real life friend of me and I want to add bots myself, but I can't really find out how..

If I do /addbot it says [botname] [skill 1-4], but it gives an error when I add a random botname. No idea what to do, does anyone know?

On Google I can only find Omnibot commands for ET ;(

Thanks in advance!
