Most universities in Malaysia don't allow online chatting in their computer labs and in the Library. The most popular instant messenger services - Yahoo, MSN and Skype, have been blocked.
However, students (like always) have found out a way to beat the system - Gmail or Google Mail.
Computer administers have overlooked the fact that Gmail users are automatically part of the Google Talk network and can chat from directly within Gmail without using a separate program.
I hope University network administrator are reading this. Oops!
