Wow! This is really easy to use. Things have really come a long way from the days (not so long ago) when "they" wanted you to learn html just to post a web page. Tools are definitely more user friendly now.
There are so many ways to use wikis that I don't know where to start the list. Book reviews, class assignments, library procedures, lesson plans--these are just a few ideas to start with. There were some great curriculum connection ideas in the California Curriculum Connections wiki. Just reading it inspires you to pick one idea and start there. It is more empowering than the feeling of being overwhelmed that I have experienced some other weeks. For some reason, these seem doable. Maybe it is because the ideas come from others in the trenches.
That said, I would still like to learn how to create and manage a wiki. I guess I'll have to figure that one out.
