Is there any way to modify the template of pages like this:
I'd like to edit the text to say "Save and edit my story"
Or similarly I might want to have a message at the top of an edit page letting folks know they can email firstname.lastname@example.org if they need help.
Do we have access to the template file for his page?
Yes, it is in the list of templates for each custom theme: users_suggestion_pages_edit.html
