I'm a TEFL teacher to teenagers and adults in Spain who's also new to this site. I'm going to try to get time to look into what you're talking about. It sounds like your students each have their computer to be online in the classroom which is not my case but I want to take advantage of new technology. Perhaps you share my feeling of being far away from the blogging, buzzing, tweeting world being in Australia.
I want more time to see messages and stuff but I'm really busy.
Hope to be able to keep in touch with you.
