Info Dear friends: we are the small, international team behind the Public Knowledge Project’s software. We are about 12 to 20 people, depending on funded projects, responsible for maintaining and improving OJS, OMP, and OCS. In 2012, over 5000 journals published at least 10 articles using OJS, reaching nearly 200,000 articles in that year alone. We estimate that there are over 1.5 million articles published in OJS journals. All of our software is open source and we will never charge for its download and use. All of our community support, including the online help forums, documentation, and instructional videos are free for everyone. We mostly rely on donations, sponsorships, and research grants. We want to ask you to make sure that we can continue to improve our software and sustain your publishing activities. If our software and support are useful to you, then please take a minute to keep them free and continually improving. Thank you.
