Viquipèdia, the Catalan version of the free, collaborative online encyclopedia, is a real success story, with almost 750,000 articles and over 1,000 active editors.

Wikipedians Xavier Dengra and Àlex Hinojo explain what drives them to volunteer their free time and contribute their knowledge to the project.

Lea Beliaeva chats to Núria Ribas, president of Amical Wikipedia, and Carme Fenoll, a wikipedian and librarian, about gender bias on the website and how Viquipèdia is trying to increase diversity, in terms of contributors and content.

This week's Catalan phrase is 'ser un setciències'. Literally, 'to be a seven-sciences', it means 'to be a know-it-all'.
