I will not dispute this. However, every contributor is expected to contribute to the category that marches with their expertise. This will for sure increase the chance of you submitting a high-quality contribution.
Utopian is open to many skills (Such as graphics-designers, developers, translators, writers and so much more) and could be used to support the open source communities/projects. All you need to do is identify the category you are most efficient with and start contributing. However, you are always advised to go through the Utopian guidelines.
Utopian value even your "ideas" made to improve an open source project. There is more Utopian has to offer. Please get in touch with us on our discord server to find out more about Utopian.
