Trouble getting ERC tracking to work when use IRC

[Chris Seberino]

ERC works great and I love doing IRC in emacs.  I tried to add ERC tracking so 
that I can be notified on modeline in other buffers when there is activity in 
an IRC channel..

I added this but I never see anything change on a modeline...

  
(require 'erc-track)
 
(erc-track-mode t)
(setq-default erc-track-shorten-names nil)
(setq-default erc-track-exclude-types '("JOIN" "NICK" "PART" "QUIT" "MODE"
                                        "324" "329" "332" "333" "353" "477"))
(setq-default erc-hide-list '("JOIN" "PART" "QUIT" "NICK"))

Am I doing something wrong?  What should I expect?

Thanks!

Chris
