Please say me, what can i do if i have CommandBook and her mute/ban cmd have more priority then BanManager?? I dont wont disabled some thread of cmdBook components, or set Low-Priority-command-registration to true, cause then i lost many useful commands... What can i do yet, if i only wont add more priority to BM mute/ban cmd then have CommandBook?

Unfortunately setting the low-priority option is the only thing you can do. Please report this as a bug to CommandBook as there's not much I can do about it.

If you don't have any anything blocking it, you should just be able to use /banmanager:command
