GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
femme pointed out on IRC that we should get @get_tor account verified. With the new request form that twitter has made, this should be easy. I'm making this ticket so I wont forget about this task.
