Usage: SAMODE <#channel> +|-<modes> [<value>]
This gives the operators the ability to set modes in a channel without being a channel operator. The modes syntax is the same as with MODE.
/samode #test +o Steve
/samode #test -i
This is a good method for taking control of any channel that is having problems. It even works if your server is currently split from services. You can fix any modes, remove or add any ops, and ban any users from the channel.
