Hi Matthew,
I just read the post from Jonathan because I was looking for a way to handle epics in easybacklog. The question is:
How do I refine a user story. Let me bring an example:
The Story is "write an email". Obviously this is an epic, so it needs more details.
First refinement:
- write recipient
- write message

In my imagination the two refinements need to be the childs from "write an email".  Otherwise, I had to create 2 new stories (write recipient and write message) and delete the story "write an email".

I hope you get my decription...

thanks a lot
