Yes, the themed weeks are no longer officially part of the resource, I'm afraid (only the gods, or
@neilarey , know if they'll be back some day. But stranger things have happened).
In the meantime, you may want to have a look at the
collections. While not being quite the same, they may hold the same kind of appeal somewhat. They can allow to organize your training around a particular idea or focus, either for practical reasons, or simply to help you get into whatever mindset you need to make things more fun.
