Relationships can make the online experience more effective, such as when web applications such as Flickr joined with Picnik to provide a seamless way for account holder to edit their photos as they store them in Flickr.

Just as in the real world, relationships change. In the ever changing online world, don't think of your accounts as memberships, because most online web applications don't seem to seem to view you as a member, just an account.

Picnik announced that it will close all free accounts, and everyone needs to gather their images before April. I wondered how this would affect Flickr, but they have a plan to have a replacement application for their account holders.

My suggestion is that you should implement the Ancestors backup plan. Have three layers of backups, especially if you believe your information is important. First, you have your original file. Second, you save this file in one other place (the parent file). Third, save the file in other place (the grandparent file). Be sure to sync those files.

Be alert to all your web applications, especially those you don't use very often. Their terms could change without much warning. Remember, it's all about relationships.

Since Glogster has revoked all free education accounts for a class, I'm recommending a few alternatives.

Glogster is just the latest in a line of websites that took away my education account after they encouraged me to join for free and use their service for free. It seems to me that the teachers who used their service and advertised for them, should receive better compensation than to lose their student accounts.

Altec's 4teachers.org has a suite of free services for teachers, and the one that is most like Glogster is called Web Poster Wizard. I've used it in the past to construct webquests, project based assignments for students.

With Web Poster Wizard, you and students can make posters. You can also create a class and keep track of student work.

Big Huge Labs has many excellent presentation tools that can be used like Glogster, yet they don't have a way for teachers to contain a class.

Otherwise, you can use the old standbys like: GoogleDocs Presentation or PowerPoint to help your students enhance their learning through projects.
