I’ve used it frequently in the past. Biz would write up tickets in our own CMS. The form would help them format their stories and would also autocomplete based on steps in previous stories.

Upon submitting/editing it would create a ticket with the story. We also ended up having it create a branch once it was scheduled by product so engineers could git checkout storyXXX and see where the cucumber steps went yellow.

There is a pretty cool SaaS product that does this now more or less that I’ve only gotten to play with http://www.simian.io/
