Wow! There is a lot of cool stuff here! I really enjoyed looking at the librarian stuff on PBworks. There was actually a page for students called "Wiki Etiquette for Students." That is definitely something we need to teach our students about. Next I checked out Wikispaces. From there I clicked under library resources and I found this neat site called Flash Card Maker. I could really see myself using this or having the students create their own cards. I also took a look at Writeboard. I think one of the neat things it has to offer is that kids can actually compare two versions of the same paper that they have written.
On the personal side I started playing around with Lulu. I had fun with the books and calendars sections. I already have a great idea for a special birthday present.
