When i need to unban someone and chanserv isnt around, what command should i use??

-Velosis

try use /mode #channel -b banmask

e.g: /mode #mychan -b westor

Really thanx. This thing was puzzling me right form the start.

How can i ban everyone whose name ends with ^ with one command?

/mode #channel +b *^!*@*
