+*** Changing or removing the IRC password
+By default the IRC server is set up to require a password for users to log in. The password is the same for all users. If you want to change or remove the password:

+#+BEGIN_SRC bash
+ssh myusername@mydomain -p 2222
+sudo control
+#+END_SRC

+Select the *IRC Menu* and then change the password. An empty password will allow anyone to log in, so you can have a globally accessible IRC system if you wish, although you might want to carefully consider whether that's wise.
