Ok, as many people know, F0 pretty much just dropped off the face of the planet (I even googled his user name, and every possible rendition of it, i'm starting to think he got hit by a car or something). Which of course, means that we need someone else to program the editor (Seeing as he was the one doing it).
As i under stand, that was disided that Ryex was now doing it (according to a post made by Blizzard on the F0 rant topic). I was wandering, does that mean it has to be built from the ground up?
Anyway, if that's the way it has to be done, i found an open source project that you can use as a starting point. the person basically tried to create an improved verion of the RPG maker series.
