Volunteer To Be a Maintainer
There are lots of things at Noisebridge that function because a few people who care about them keep them running. Volunteering to be a maintainer for something you care about is a great way to contribute. Generally, if you want to become a maintainer of something with none, get in touch with the other maintainers if there are any, put your name down on the list and speak up at a meeting announcing that you've volunteered to help maintain something and ask for more volunteers if you are still below 2 or 3.
