Stixy is a fun and easy way for students and educators to collaborate online. Stixy reminds me of Wallwisher, but has many more options for sharing. Start out with a blank virtual bulletin board. Use the Stixy widgets to add content or functionality to your board, positioning them anywhere. Users can add notes, photos, documents, or to-do items. After content has been added to a board, it can be shared with others of your choosing. Those that have been invited to the Stixy board can be given permission to add content, upload, or edit.
The ability to make changes to the document is an issue for me. We are using Sign Up Genius at Northside. When parents sign up, they provide their email address and they get a reminder a few days before the conference (actual # of days is set by teacher). SU Genius integrates with Google Calendar too! Our guidance counselor used it for her monthly guidance lesson sign up. Participants can go in and change time slots if they need to. I schedule SRI testing with Sign Up Genius. Can you tell I love this site?
