I still don't see the Story Points field when creating/editing stories.
I followed the GreenHopper 101 instructions and set it to use the scrum template. According to GreenHopper 101 this shoulld cause the project to be "automatically configured to use Stories, Epics, Story Points, Ranking and Flagging."
I do see Story Points in the field configuration list under Administration. I guess I could play around there to add the field to the screens, but want to make sure I didn't somehow miss a step in setup.
