Buddy Spy is a monitoring system that you can use to see who is hiding on Yahoo Messenger, and in which chat room.

The installation is simple and fast, with no special remarks to take into account.

Although the concept of Buddy Spy is a little childish (i.e. spying on your friends), the interface of the software is somewhat professionally looking (probably suggested by to the white and blue color scheme), where the buttons and content are well organized.

The left side of the window shows two main menus - Tasks and Miscellaneous.

In Tasks, you can configure your Yahoo Messenger user settings, connection setting and bot status settings, while scanning for one or several persons (by making a list).

Besides the online status, you can check up on their chat status, webcam status, and which room they are chatting in. There is also a scan history page where you can keep track of the friends you have spied on.

The Miscellaneous section presents general information about the program, help, automatic update, and "make a donation" button.

The software seems to work well but it has some occasional periods of time when the wires are all wrong (this is probably an internet connection issue). Most of the times it works perfectly.

So basically, if you want to play Sherlock Holmes and catch your friends in the act, then feel free to check out Buddy Spy. It is highly addictive for the first couple of days.
