Code review comment for lp:~unity-team/ubuntu-system-settings/welcome-wizard

Thanks for the update. Laney added a library for accountsservice (see https://code.launchpad.net/~laney/ubuntu-system-settings/as-library/+merge/200646) ... could you update your code to use that one (see https://code.launchpad.net/~laney/ubuntu-system-settings/private-as-background/+merge/200648 for an example of client)
