BuddyCheck 1.0.3
Description:
BuddyCheck will show you the real online status of your Yahoo! Messenger friends. It will regularly check to see if they are online, even if they are invisible or are using Stealth Mode. It will notify you using a tray area balloon when a contact signs on or off. It does this by sending special messages to the Yahoo! Messenger server from a separate account which you must create.
