Is it possible to run storytld on an IIS server?
I'm not aware of any IIS setup of storytlr. Although it should be possible in theory (it is just Php/Mysql), I think you'll find many little things hardcoded in there that expect to be on a linux host. Things like paths, or php libs like gd, mcrypt, etc.
If you give it a try and get stuck, let us know and we can try to help,
