Join

Join is the command used to join a channel. It has the following format.

/join #chan

There a few cases where this command will not work. These cases are when the channel is invite only, a user is banned, or the channel has a channel key.

If the channel has a channel key, the following command must be used.

/join #chan channelKey

If the channel is invite only, use the following command and wait for another user to send an invite.

/knock #chan Message to channel ops.

If the user is banned, I am banned is hopefully helpful.
