Yahoo! Messenger for the Web lets you chat, download-free, on the Y! network right inside the web browser.
Years ago…Yahoo had web based messenger that was built on java..but then they removed the service…
Now its back again with more enhanced UI built on Adobe Systems Inc.’s Flash. But yet it does not provide advance feature such as webcam and file tranfers. Yet it has the cool features such as notifications, tabbed interface, save message history in yahoo server..etc..
Messenger for the Web is also compatible with Microsoft Corp.’s Windows Live Messenger.
