Every 3-4 months, Puppetlabs has a Triage-a-thon.
It’s a cool opertunity to get your hands dirty looking at the puppet source code, help fix some outstanding issues and generally help out the community.
Everyone jumps on IRC, and you can fish through the Puppetlabs Jira and find out what you can fix, and sometimes just do a bit of janitor-ing removing old tickets that are resolved or nudging people for reviews and the like.
