What I love about wikis is how fast you can create one. It's takes just a couple of clicks and you're up and running. A couple more clicks and your website has content....they're just so easy.

Using Private wikis for personal use is a great way to quickly inventory your school or classroom. Create a private wiki for your grade level or classroom and then create a simple table to keep track of your inventory. When your team members and you can easily edit the inventory it makes planning for next year a cinch!

I'm not sure how many private wikis I have....but when you can set up one in the middle of the meeting...have everyone join and then create on the go...it's almost too easy.
