MSN Messenger Force uses the MSN Messenger protocol for core instant messaging and presence functionality. The MSN Messenger Service tells you when your family and friends are online so you can send instant messages to them in real time. MSN Messenger Force for Windows-powered Pocket PCs allows users to be notified when their contacts come online so they can communicate with them via short text messages. A new Scribble feature allows users to also send drawings and sketches as instant messages, adding a new dimension to instant messaging. This version additionally includes support for GPRS, Wireless LAN (IEEE 802.11), and Ethernet cards.
