How do I register a channel?
Step 1
First, join an empty channel, like this:/join #YourChannel
where YourChannel is the channel (room) you want. You can't register a channel that's already taken.
Step 2
In order to own a channel you need a registered nick. If you have not registered your nick yet, type:/ns register password email
Wait until you get an email from NickServ, then read it. For more help, see /Registering Nicknames
Step 3
Type this:/cs register #YourChannel
Your channel is now registered.
Should I go and tell everyone about my new channel?
No! This is considered rude and will get you banned from most places. Only tell your friends, privately, or advertise it in #promotion.
How do I change my channel topic?
Your channel topic shows up next to your channel in the channel list, and at the top of the screen. To change it, type:/topic #YourChannel This is a topic.
Or, if you're using mIRC or xchat, you can double-click on the text area to bring up a window which allows you to change your topic.
