Why somebody should help ?
GimpShop fork attracted interest only because offered a single window interface...
but now also Gimp has a much better implementation of single windows mode as option (the old mode is still available you may switch with a click)
you don't even have to wait the official release of gimp 2.8 to test it, there are Windows installers available (32 or 64 bit ) of gimp -2.7.4 (beta) here
www.partha.com Gimpshop was a very poor hack , so buggy that was almost impossible to use, and based on a obsolete version of gimp
i really cannot see any reason to resurrect that dead fork , what could offer is already integrated in the new GIMP
