Ewgie is a small, simple collaboration service, very much like IRC (Internet Relay Chat). It's easy to learn for people new to it (see documentation at http://www.eso.org/astronomyonline/communication/ewgie/docs/), and commands for IRC users have been provided so that net veterans should be pretty comfortable with it. Ewgie is unique from other similar chat services in that:
It is compatible with Netscape Navigator 3 on Windows, UNIX, and Macintosh platforms and Microsoft Internet Explorer 3.
In Astronomy On-line we offer three different rooms where participants can meet on-line and share their ideas by putting them onto the whiteboard. Enough said now... just and login to Astronomy On-line Ewgie
