In case you are interested there is a website, in Greek, that supports teachers of Greek language that work abroad in universities. It is the first attempt to create and support a learning community.
You can find it in http://www.komvos.edu.gr/fryktories/index.php
It is called Fryktories, like the ancient communication system based on fires. You can find a forum there and articles archives. Lately, the members are trying to create a "Text archive" as they call it so that everyone abroad can organize lessonplans based on that texts.
