Hello public school teachers!
A few years ago I worked at a Korean public school. The school used a pop-up messenger service which allowed teachers to quickly send messages and files between staff and departments.
Can someone tell me the name of the service so I can pitch it to my new school??
Or, if there's a western version of the same service that you know of...that would also be useful. Google turned up a program called LAN Chat Enterprise, but it doesn't look that professional.
