@ademalsasa have you checked the work of Framasoft? They have been offering truly amazing Libre/Free services, and have also been maintaining a directory of FLOSS tools for many years ;)
@yaglb thank you for sharing Framasoft with me! Wonderful, yes, I have checked them and you links are useful to me too.
For people who care about, support, or build Free, Libre, and Open Source Software (FLOSS).
