    added this pointer:

    • Andrew Kresch, On the geometry of Deligne-Mumford stacks (doi:10.5167/uzh-21342, pdf), in D. Abramovich, A. Bertram, L. Katzarkov, R. Pandharipande, M. Thaddeus (eds.) Algebraic Geometry: Seattle 2005, Proceedings of Symposia in Pure Mathematics Providence, Rhode Island: American Mathematical Society, 259-271 (pspum-80-1)

    Was looking for references to point readers to for background on the idea that DM-stacks and orbidfolds are essentially the same thing, realized in two different geometric categories (up to a list of inessential technical conditions). This is the best I have found so far. If anyone knows further references along these lines, please drop a note.
