I have always heard people talk about it, but never really bothered to check it out.
Our presenter at a tech workshop, John Kuglin, introduced it to me, and I LOVE it!
Here's one that I started. Still have a lot more sites to add to it!
I also have one that I embedded on my Class web page with the tech sites we use in the classroom. You can add videos, documents, forms, whatever your heart desires. AND, it's all in one place!
Imagine the possibilities!:)
