Madmagz is a neat platform for collaboratively creating online magazines. Madmagz provides you with a magazine template that lets you use images and text that you can edit alone or with invited collaborators. Unlike some other collaborative writing platforms, the original creator of the magazine has to approve or verify submissions from collaborators. When I was testing the platform I found the need to verify every change a little annoying, but I can see how many people would like to have that level of control over the editing process.
Publishing your Madmagz online is free. If you want to download your magazine as a PDF, you will have to pay for that option.
Applications for Education
Madmagz could be a good platform for creating an online school newspaper. Similarly, it would be good for creating a classroom newsletter in which students summarize the highlights of the month in your classroom.
