22. - Things - MSN messenger is great. I use this at home to communicate with friends and relatives. I even have a webcam. This is a great way to communicate as I talk to my cousin in Malta. This way we are able to keep in touch and see each other.Libraries could use this function to communicate with other Libraries to get a quick response as they know the person is working and logged on. When they leave their busy, they would generally sign out or put 'busy' or BRB.
