Yes, I understand better how that idea could definitely enhance the user experience and the community sense on a site. Trying to follow up on the "what-could-it-do-without-chat" question, I was thinking of a Delphi like system where you would not only know who's online, but get a historic of the last visits (along with login/logout times). I think this maybe could be combined with your pal list. I don't know about feasibility tough :-\
