Re2o is an administration tool initiated by Rezo Metz and a few members of other FedeRez associations around the summer 2016. It is intended to be a tool independent from any network infrastructure so it can be setup in "a few steps". This tool is entirely free and available under a GNU Public License v2 (GPLv2) license on FedeRez gitlab. Re2o's maintainers are volunteers mainly from French schools. If you want to get involved in the development process, we will be glad to welcome you so do not hesitate to contact us and come help us build the future of Re2o.
