SUL3 is deployed. Login is working better. If you try to login from allthetropes.org, however, the styling is currently missing. This is because it tries to load CSS from All The Tropes on top of the login page, and the content security policy doesn't like that. Logins seem to persist really well across top-level domains, however, which is good news for those of us using more than one wiki.
