Well.... that is a bother.
Isn't there any sort of disclaimer in the content submission process to say that editing to existing content may be necessary at a later date? Some sort of clause whereby more content can be connected to the existing stuff without explicitly hunting down permission...
I won't ask if anyone remembers me from FutanariPlanet ... It doesn't really matter either way.
Point is I've been in lurk-mode for a few years now... partly in shame since I'd started making my own game back in the "unnamed text adventure" days and ended up losing it all to computer hardware...
