Both software packages have easily readable and almost identical interfaces, making it easy for occasional users to find their way around. The web-based applications are accessible via any popu- lar web browser. To prevent unauthor- ized users from changing entries at will, both applications are password-pro- tected. Because the Shuttleworth Foundation wants to give users access to applica- tions in their own language, SchoolTool and SchoolBell have been translated into other languages, which means that Figure 1: Edubuntu is Linux for school children.
