[Pharo-users] Slice for a non Pharo package ?

Hello, I reported a bug on Athens here : https://pharo.fogbugz.com/f/cases/15640/ I also created a slice to solve it by following the Pharo fogbugz video tutorial. But then I realized that Athens is not present in Pharo/main so it would not make sense to commit the slice into the Pharo Inbox. What is the procedure to propose a Slice for a package outside Pharo/main ? Sorry if it's a dumb question :s Cheers, Matthieu
