Looks like this Challenge idea is coming to fruition, after some more approvals it may be going next month.

I've changed some of the parameters to make it easier on everyone. It is still for a 24" x 36" map, however the minimum resolution requirement now is 100 ppi (but will accept up to 300 ppi, for those who can do this...)

So a 2400 x 3600 pixel map is not as taxing to your PC to make your map entry. If your comp can handle a file this size at higher resolution, go for it, just don't feel you have to create 300 ppi and drop a couple more RAM chips just so you can do it.
