We discuss stringy functors from the pull back point of view of Jarvis-K-Kimura and the push forward point of view of our orbifold Milnor ring constructions. We show how these approaches merge to give a de Rham theory and apply back to singularity theory. If time allows, we also give results on global gerbe twists and the Drinfel'd Double.
