I am pretty sure as you introduce the idea to your students everyone will want to have a say in their next e-magazine. There is nothing much more rewarding to students then to have a proof of their hard work recognized in a publication of some sort.
Most of the tools cited here are easy to use and have user friendly interface and they will let you create your own e-magazine or newspaper in few simple steps. Yet I would recommend your discretion as you use them with your students.
