Stixy.com is a collaboration Web 2.0 tool that can be used to create your own online "bulletin board" with notes, photos, a to do list, adding documents and much more. You can share with others and allow them to add their own information or make it private. Think of all the things you can do for students to journalize what they are working on, for a project. Consider it a journal of learning, or self-assessment of your work. Teachers can use this tool for pre and post assessment.
Be careful, there is a limit to photo size and document size (50 mb). But you can create as many stixy boards as you want. Look at https://www.stixy.com/sample/photo_album to see an example. Go to https://www.stixy.com to get started. Once more, it's free. See below for a picture of it. And this link is to a document that explains it. But it's the same explanation as on the site. Have fun.
