You know how when you text, whenever you write something it's in a clear little bubble and when someone responds, theirs is green? Can you change the colors of those? If not, I think it would be cool to add that option in a future software update. Also, I'm new to Macs and just got a MacBook. I also noticed that it's the same way during iChat, except with different colors. How does the computer decide which color to assign to different people on your buddy list?
