Ask HN: How do technical non-developers help with open source projects?

I used to code for a living but decided that I enjoy being a technical writer and PM much, much more.

Things I enjoy:

  * Writing detailed functional specifications.
  * Creating wireframes & mockups.
  * Creating flowcharts, BPMN docs & graphs to explain a project.
  * Planning Poker, Creating sprints.
  * Discussing technical issues with developers.
  * Simplifying technical issues for customers.
  * Learning about new technologies.
  * Explaining new technology to customers.

My question is; Is there a need for someone like me in any open source projects and if so, how do I contribute?
