Enterprise Express Messenger ( EEM) is a LAN/WAN instant messaging software designed to assist people in their day-to-day internal communications. EEM facilitates communications by providing a rich user interface and fundamental functionalities as sending instantaneously messages, files, screen captures and URL. With EEM, information is exchanged directly between users (point-to-point communications) thus unloading your current emailing infrastructure. EEM is easily configurable and does not require any server. Working on its own messaging protocol, EEM cannot be infected directly by email viruses and is also spamming free. The "EEM Express Board" has been created to provide a very quick access to all your colleagues and by the way becomes the easiest and fastest way to reach them! The "EEM Message Board" informs in real time of all arriving messages, images and links. You can read/view them and quickly take action. It is a functional form that can be located anywhere in your screen. The message board is displayed only when a new message/image/link arrives and will disappear at your convenience. The "EEM Message Center" is one of the EEM centerpieces. It is a kind of control center from where you can access all functionalities and track any events that occur while you are working. Enhanced capabilities for sending files have been implemented making it easier to exchange files between users (as simple as dragging a file from Windows explorer and dropping it on a username). You can now send a copy of your current screen to any user by a single click. This functionality is very useful for by example debugging purposes, call center and any collaborative works.
