Hi. I am playing with my new MBP and wanted to know if iCHAT supports talking to buddies from Yahoo Messenger too, just like it does for AIM? I got the AIM one to work, and it says something about something called Bonjour (?) but nothing about Yahoo? Please let me know how to set this up as possible, that way I won't need separate programs for AIM and Yahoo Messenger. PS- Does windows media player have a program for MACs? If not, whats the best program similar to Windows Media Player that I can use to view all the same video types as that? Thanks!
