I'm glad the group got up and running, since I was the one who originally  
mentioned it.  I use a plug-in called Jscrob for Windows iTunes that does  the 
same as the iScrobbler for mac.  Everytime I hook my iPod to the  computer, it 
automatically updates my last.fm with everything I've listened to  since the 
last time.
 
The group charts should be interesting to see.  I was thinking of  posting a 
weekly or monthly chart here as well.
