How to use IRC

If you're new to IRC, then I'm pretty sure you don't really know how to use IRC. The good news is that it's quite easy.

Basic IRC Commands

/connect
This can be used to join a server. Example: /connect irc.example.com
/join
This can be used to join a channel. Example: /join #examplechannel
/nick
This command changes your nickname. Limited to 9 characters. Example: /nick newnickname
/msg
Can be used to start private chat. Format: /msg nickname message Example: /msg bob Hello, you good today?
/ping
This command gives you the ping time, or lag time, between you and the person you pinged. Lag can be explained as the amount of time between when you entered your message and for other people to read your message. Example: /ping nickname
