Contriving

From the article:
Don't alienate volunteers — everyone in the R community is a volunteer, and it doesn't benefit the community when you're unnecessarily rude.
Understand volunteers have other commitments — while the core R team is doing an excellent job building a statistical computing platform, not everyone can make the same commitment to an open-source project.
Open-source has limited resources — every contribution helps.
Be patient — not everyone can operate on the same level, and new members will need to be brought up to speed on best practices._
