*headdesks* and somehow I think this is exactly what I need.

I love git because it's so powerful, just like the rest of *nix. No matter how long I use it something always makes me feel like a n00b.

the problem is that I only half understand what git is doing, just enough to attempt a communication of what I want to do. It doesn't help that I'm not the expert on the other side of this problem either.

thanks for the help guys, even if I do come off like a moron.
