+There are, however, many other areas where you can contribute to a

+
+* Documentation
+* Marketing and social media promotion
+* Event planning
+* Technical support on mailing lists and other forums
+* Vendor/Sponsor relations
+* Project management (organizing the next sprint or feature set, keeping
+  track of who is working on what, updating the roadmap)
+* Community management

+Projects should identify, recruit for, and celebrate contributions in
+all of these areas, and reward non-code contributors with the same
+rights and privileges that they do for code contributors.

+**Being a committer is *not* just for code contributors!** It's a
