can't hg push my changes - account created with github
I created an account with github. I can fork, clone and commit but I can't do hg push.
$ hg push pushing to https://email@example.com/jpcaruana/modoboa searching for changes http authorization required realm: Bitbucket.org HTTP user: jpcaruana password: abandon : HTTP Error 412: Password required
ps : I'm new to hg and it was the only way to propose work on modoboa project
