We'd like to invite young people associated in non-governmental organizations, informal groups, dialogue bodies and activists acting on their own to free online training sessions on disinformation, recognizing it, preventing and counteracting its negative effects. The training is addressed to all those who understand the importance of disinformation in public life, who would like to learn more about the ways it works, get specific tools of recognition and methods of dealing with it. We also invite people who actively participate in public life (also at the local level) and therefore are most vulnerable to disinformation actions aimed at undermining their credibility and the trust of public opinion, necessary to effectively fight for the public good or the interests of the groups they represent.
