Great! I've just sent you an invite to the Google Code-In mentor interface. We'll soon send an informational e-mail, but the most important bits are already outlined at https://www.mediawiki.org/wiki/Google_Code-in/Mentors. You can direct any questions at Wikimedia org admins, who can be contacted via email@example.com. Thanks for mentoring! PS: I've already imported all Phabricator tasks into GCI interface, You might need to uncheck "my tasks" at the bottom of tasks list in the GCI interface in order to see them. Feel free to review the ones in your area of expertise, and assign yourself as a mentor to them.
