I am an addicted Wikipedia contributor, mostly for the Portuguese and English versions. I make punctual interventions in the Spanish version, and I expect do the same for Swedish version soon. The topics of my interest vary a lot, and include olympic sports, geography and recent events.
I am also a sporadic contributor to Commons, the open audiovisual repository from Wikimedia (the non-profit organization that also maintains Wikipedia). I draw coat of arms and sport clubs badges as a hobbie.
I am a KDE user since version 1. For some time I tried to support the project with small code contributions.
Now I support it with sponsouring and by advocating the coolness of KDE software.
