 The C region is a region thriving with collaborations with many communities and organizations working together for more than a decade now, organizing together events, projects and knowledge transfer for the region. And one of the most important focus of the region is working together on campaigns. The C region has been a really important organizer of campaigns for a long time. Campaigns like C-Spring, One Le Bon Rav, Wikilev's Earth have been models for the rest of the world. And the shared history and culture of the C region, but also the diversity of languages and cultural differences in the region make a really neat opportunity for using these campaigns to exchange and document different parts of the region and different languages. C-Spring is a writing campaign uniting up to 30 communities in the region. For 10 weeks, the communities from the C region are writing articles about each other and bridging knowledge gaps between them. The campaign started in 2015 and it mostly featured communities that were the most active at that time or had some past experience in working with the environment. But then the concept gradually developed so that other groups cannot participate in communities during the contest. And I have to say that we really make a big effort in engaging underrepresented communities from the C region. 30 language communities participated in C-Spring, which is really a good number and shows about diversity as one of the main goals of the contest. The C region consists of communities which share a lot of commonalities, like similar past and similar traits. But at the same time, the idea is that every community is unique in some way and we have many differences that have to be pronounced in order to promote our diversity as a region. So I think that C-Spring is exactly the kind of activity, the kind of project which pinpoints this diversity. Because we aim to involve as many communities as possible. One Leap One Drive campaign is a clever way of inviting librarians over to being editors of Wikipedia because all librarians are very comfortable working with references, with bibliographic notes and just spending a little bit of time to take that knowledge and put it into better articles for the whole community to access. I think it's actually the description of the librarian's job. This campaign is dedicated to increase reliability of Wiki projects and also to show librarians how important their role is in the media world, but also to show them how rich their environment is and how to use it to make Wikipedia and other Wiki projects more reliable. One Leap One Drive started in 2016. We joined in 2018. We have added because of this campaign more than 46,000 references and that is only on Serbian Wikipedia. Romanian librarians editing One Leap One Drive now has a history. It started with me joining the movement a few years back, but every year we organized some kind of event for librarians to participate. Even during the pandemic, we didn't do one Leap One Drive per se, but we did trainings and meetings with librarians, so they better understand the potential of Wikipedia and how they can contribute to it. We had 29 editors this year, which for us, it's a great number because mostly of them are coming from small communities throughout the country. It's a great improvement, but the number of edits that we had, it's 10 times bigger than we had last year. One Leap One Drive campaign has such good results in Serbian region is because we had a really good cooperation before One Leap One Drive. We have so much other activities besides One Leap One Drive like Sea Spring or Sea Meeting. Now we have Sea Hub, which will bring us even more close together. Hi, my name is Natalia.
