Education Grid

EducationGrid is a free program online that was designed to be an educational tool for all ages. Each user must use verified credentials and their own name as a username. It was announced in 2007. It can be very customizable based on the user. There is a small bit of controversy with having this virtual education environment because of what younger students may encounter during their time online. It is open source and you can use anything created on this platform on any other platform.
