the way users e-mail address request extended permissions on email field. user must allow see , cannot e-mail addresses of user's friends.

http://developers.facebook.com/docs/authentication/permissions

you can if using facebook connect passing scope=email in string of call auth dialog.

i'd recommend using sdk instead of file_get_contents makes far easier perform oauth authentication.

mercurial graft feature, can it copy? -

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
