Just to clarify what you are doing . . .
I've been trying Git in... solo mode
Because of the way Git tracks changes,
it's easiest to create an iProject and let Git track the working iProjects directory, where the source members exist as stream files.
Are the "stream files" you are talking about . . . those files of RDi source that is stored on your PC, or are you talking about storing your files on the IFS ?
