 ## Calls for Testing
-
 An important step for RFC implementation is for people to experiment with the
-implementation and give feedback, especially before stabilization.  The following
-RFCs would benefit from user testing before moving forward:

+If you are a feature implementer and would like your RFC to appear in this list, add a
