This can be something useful sometimes to tell what you are proud user of 
(eval-after-load 'rcirc
'(defun-rcirc-command sv (arg)
"Inform other people of what IRC client you are using."
(interactive "i")
(rcirc-send-message process target (concat "Proud user of " rcirc-id-string))))
Launch it in a rcirc buffer either with /sv or M-x rcirc-cmd-sv RET
