Should I register my nickname?
If you plan on chatting regularly, under the same name, registering your nickname is a good idea, provided you are going to remember your password and be ready to in put it when you log on.
How do I register my nickname? To register your nickname type: "/msg nickserv register yourpassword youremail"
Example: /msg nickserv register peaches firstname.lastname@example.org
Be sure to use your real email address, as that is the only way for you to regain your password if you forget it.
How can I protect my nickname?
On our chat network, Geekshed, you don't have to identify yourself unless you want to. However, if you have a special status in a room (such as op or hop) that won't be recognized until you identify yourself with your password.
To protect your nickname type: "/msg nickserv set kill on" without quotation marks. This will give you 60 seconds to identify yourself before changing your nickname to "Guest." Turning this feature on keeps people from using your nickname without identifying.
Example: /msg nickserv set kill on
How do I identify myself? To identify yourself with Nickserv type: "/msg nickserv identify password" without the quotation marks, and replacing the word "password" with the password you set when you registered.
Example: /msg nickserv identify peaches
