@DarioLodeiros @pedrobaeza as PSC, your comments would be appreciated.

Hello, I confirm @marcelsavegnago from Escodoo is a very serious and responsible OCA contributor and that he has a valuable experience and usage of the helpdesk modules, so having it in the helpdesk PSC is a big advantage for the OCA, especially as the helpdesk maintainers aren't so active these months, so it's not like he would be disputing design decisions with other very active members.

BTW we are very proud the Brazilian localization is now advanced enough to see new very active OCA contributors from Brazil such as Marcel or also the very serious contributors from Engenere. We expect more OCA contributors from Brazil in the coning years.
