Hello Mario,
You have posted this into the feature requests area which is an unsupported section of the site. It is meant for users to submit for idea and it is only for us to collect these ideas whenever we are working on a new feature.
Please take note that "Supporter" is not from our support team. It is only his nick name. Supporter, can you kindly please change your nick name as this is confusing other users on our site.
As for the feature that you are looking into, EasyDiscuss is not a feature request system. It is meant to be a forum / discussion system. You can activate the voting feature which in place allows users to upvote on a discussion. You just need to ensure that votings are enabled for EasyDiscuss,
