mIRC is only the method (vehicle?) used to connect to IRC networks and join channels, nobody here has any control over those networks or channels. If you can't contact the channel owner to find out why they banned you from their channel, try joining the networks help channel and try asking an IRCop if they can tell you who the owner of the channel is and how to contact them. It's beyond the control of anyone here, sorry. If the advice given in response to your last post is useless to you, I'm sorry but I'm afraid there is nothing anyone here can do to get you unbanned from that channel and all we can do is give the best advice possible to get the ban removed.
