What are the criteria for a new file submission falling under the Original Aircraft category vs. the Repaints category? I've seen several cases recently (today's: http://library.avsim.net/esearch.php?DLID=...CatID=fs2004ac) of decidedly non-original aircraft in the Original category.

Original aircraft are made from the ground up. So if you make a B727-200 say and design every part of it from scratch and did not use any thing from any other aircraft at all not even the textures that would be considered a original aircraft. If you take a existing aircraft and say give it opening cargo doors or working Stairs that would be a modification. And of course a repaint is nothing more than just Textures to use on a existing aircraft.Gary Buska Library manager AVSIM ONLINE :-)
