You don't actually have to talk to anyone of us to start contributing. Get a working environment, go in to mantis and start to work on the bugs we have there and add it to our project. One of our devs will look the code over and if it looks good, it will be merged to Nova. One way to go is to contact one of our QA on discord and start a conversation with one of them. They will be better suited to guide you through what mantis bugs that should be prioritized and how to commit code. All our QA submit code to the project.
