Forums mIRC Help Unregistering/Deregistering a channel HELP

I was wondering if there was a command to unregister a channel if you are the channel founder?

This is a IRC network specific question. You need to ask on the help channel for the network, or check the website for the network.

In general, if there is a command to register a channel, there is a command to remove that registration. On DALnet for example the DROP command exists.
