The description of fbQuick - Play With New Friends
One of the disadvantages of using Facebook instead of an instant messaging service is that you have to access the website to know the news about your friends.
fbQuick is a free application that allows us to know if any friend has changed status or written a comment without having to enter the website. You'll receive all notifications as if you were using a common IM client.
The notifier will notify you in case of a new message in our wall, private messages, tagged in a photo, friend requests... you'll see a message box appearing in the lower right corner of the screen.
In the control panel of the program you can set different parameters such as the frequency of the advises and set the messages you want to see.
If you want to stay on alert and know everything about your friends activity on Facebook, FBQuick is a good choice.
