this already came up and its a good idea except some people don't quote all the time.
I was also thing you could have a notifications type thing except it would be for your threads, so when you make a thread and some one postes in it you get a notification. There could be a 4th tab next to the "logout" "friends" and "quicklinks" tab. it could just simply say notifactions. Then once you click on it, it could have the name of the thread, who replied, and what time, ect... This would be very usefull in bst when someone postes in the thread, because you get side tracked and forget about people posting in it.
This Would Be A Great Idea For Everytime Someone Comments On A Photo, Video, Feedback, Etc.
