how do i make a irc channel?
Using mIRC, connect to any IRC server and then type the command:
/join #YourChannelName
you will be automatically opped, and if that network has any services like NickServ/ChanServ you can register your nick and channel
/msg nickserv help register (for more)
/msg chanserv help register (for more)
Any further help can be acquired at the networks designated help channel.
It's a good idea to browse the forums sticky threads before posting.
This sticky has a bit more information and links.
