acknowledged successful identification."

I want test it

#+begin_src elisp

    (message "Network: %s" network)
    (message "Nick: %s" nick))

I get the NickServ notice:

-NickServ- This nickname is registered. Please choose a different nickname, or
	   identify via /msg NickServ IDENTIFY my_nick <password>
-NickServ- You are now identified for my_nick.
