Wikis!

I've actually used wikis before - once to share recipes with my family and once to plan our honeymoon. I've switched over to Google Docs for collaboration, but I think wikis are a bit more flexible. I can definitely see applications for our work. Perhaps teachers in a course could complete a wiki for other educators about a particular topic, or about ways to globalize your classroom, as part of course assignment. You could even include student work samples. It would be a great marketing tool if we ended up with a polished site, as well.
