Writeboard

I found this tool (part of what we now call Web2.0 or the Read/Write Web). It is free and really cool. Since we are writing teachers, it has a lot of bearing on what we could do in the classroom. Even if we just used it a few times the students would gain from it. This is what their website has to say:

"Writeboards are sharable, web-based text documents that let you save every edit, roll back to any version, and easily compare changes. Use Writeboard to write solo or collaborate with others."

I say it is worth a try.
