SchoolRack enables you to set up classroom portals for your students and parents to use. There is a reasonable selection of included themes to choose from.
Each student/parent creates their own individual account. They can then search for and join their school as well as joining your class group (either manually or through a generated code).
Not only can you post assignments for students and parents to read and download, but you can also use the inbuilt discussion board, calendar, internal messaging and online assignment collection and assignment grading feature.
It is, also, very easy to include any embeddable content, such as videos and widgets, from other websites. All these features, help to make SchoolRack a dynamic two-way learning platform, which can be used inside and outside of the classroom.
Your published site, including added files etc, is publicly visible and can be accessed by anyone who knows your website address - in the form of http://schoolrack.com/sitename
This also applies to the topics on the discussion board, which can be read by anyone although only your group members can contribute to the discussions. It is worth noting that 'password protected sites' are available for the paid version but not for the basic free version, being reviewed here.
SchoolRack is very easy to use and for those that have not gone down the Moodle route (or something similar), then SchoolRack has plenty to offer!
