EPeg

Epeg is a simple to use staff in/out board and more.
With EPeg you can chat with co-workorders, see at a glance your co-workers status, take phone messages for others and keep track of the time you spend on the phone with your customers.
It only takes one click of the mouse to bring up the tray menu to change your status and one more click to change your status.
Need to take a message for someone that is not available to take the call? Just right-click the EPeg icon in the system tray and click "Take Message", a simple phone message form pops up. You fill out the details and click save. Instantly the message recipent gets the message delivered to their desktop.
Even if the intended recipent's computer is off (or EPeg is not running) as soon as the recipent starts their computer, any messages waiting for them will pop up on their screen.
EPeg does not require a dedicated server as there is no server required. All that is needed to use EPeg is two computers. No need to "Set up" the system or the users as EPeg does all this automatically.
