I have managed to post my paper "Omega Categories I" on the math archive: http://front.math.ucdavis.edu/math.CT/0404216 A number of small changes have been made as compared with the undated version of the paper which many of you have: spelling errors and some notational errors have been corrected, the diagram associated with the definition of omega pseudo-functor on page 36 has been corrected, section 9.3 has been shortened and strengthened while a new but obvious result has been added to section 9.5 Carl Futia
